Answer:
a) Check Explanation
b) The p-value obtained is greater than the significance level at which the test was performed, hence, there isn't enough evidence to support the claim and conclude that the mean delivery time for Domino's Pizza is less than 30 minutes.
Explanation:
a) The assumptions required to conduct a suitable t-test about a mean include
- The data must be obtained from a random sample of the whole population (simple random sample).
- Individual sample data values are expected to be independent of one another.
- The sampling distribution should be normal or approximately normal.
b) For hypothesis testing, the first thing to define is the null and alternative hypothesis.
The null hypothesis plays the devil's advocate and usually takes the form of the opposite of the theory to be tested. It usually contains the signs =, ≤ and ≥ depending on the directions of the test.
While, the alternative hypothesis usually confirms the the theory being tested by the experimental setup. It usually contains the signs ≠, < and > depending on the directions of the test.
For this question, we want to investigate if the mean delivery time for the Domino's Pizza is truly less than 30 minutes.
Hence, the null hypothesis is that there isn't enough evidence to conclude that the mean delivery time for Domino's Pizza is less than 30 minutes. That is, the mean delivery time for Domino's Pizza is greater than 30 minutes.
The alternative hypothesis will now be that there is significant evidence to conclude that the mean delivery time for Domino's Pizza is less than 30 minutes.
Mathematically,
The null hypothesis is given as
H₀: μ ≥ 30 minutes
The alternative hypothesis is given as
Hₐ: μ < 30 minutes
To do this test, we will use the t-distribution because no information on the population standard deviation is known
So, we compute the t-test statistic
t = (x - μ)/σₓ
x = sample mean = 28.5 minutes
μ₀ = The standard we are comparing against = 30 minutes
σₓ = standard error = [σ/√n]
σ = Sample standard deviation = 3.5 minutes
where n = Sample size = 16
σₓ = [3.5/√16] = 0.875
t = (28.5 - 30) ÷ 0.875
t = -1.71
checking the tables for the p-value of this t-statistic
Degree of freedom = df = n - 1 = 16 - 1 = 15
Significance level = 0.01
The hypothesis test uses a one-tailed condition because we're testing only in one direction.
p-value (for t = -1.71, at 0.01 significance level, df = 15, with a one tailed condition) = 0.053932
The interpretation of p-values is that
When the (p-value > significance level), we fail to reject the null hypothesis and when the (p-value < significance level), we reject the null hypothesis and accept the alternative hypothesis.
So, for this question, significance level = 0.01
p-value = 0.053932
0.053932 > 0.01
Hence,
p-value > significance level
This means that we fail to reject the null hypothesis & say that there isn't enough evidence to conclude that the mean delivery time for Domino's Pizza is less than 30 minutes.

youve got your budget, credit history and savings in order. Whats the nest step
After having your budget, credit history, and savings in order, you may apply for a loan. This process involves providing job and income details, allowing a credit check, and may possibly require a cosigner or collateral.
Explanation:Once you have your budget, credit history, and savings sorted, the next step in the financial capital market would be to apply for a loan if needed. This involves filling out forms regarding income sources for prospective borrowers. The bank then conducts a credit check on your past borrowing.
A few additional steps are taken by banks in some cases. One of them is the requirement for a cosigner on a loan, which is an individual or firm that legally pledges to repay some or all of the money if you fail to do so. Another approach banks sometimes use is requiring collateral, often in the form of property or equipment that the bank has a right to seize and sell if the loan is not repaid.

Tom is retired. He receives retirement income each month in the amount of $2500 as well as Social Security income in the amount of $1200. Tom owns 4 rental properties that he receives $1680 in rental income each month on each rental property. Tom has mortgage payments in the amount of $3200. His wife drives a Lexus with a $540 car payment and he drives a Buick with a $395 car payment. What is Frenchy’s debt to income ratio?
Answer:
77%
Explanation:
The formula for calculating the debt to income ratio is:
Total monthly debt/total monthly income.
Therefore, we have to calculate the total of monthly debt and monthly income first.
Monthly debt:
Mortgage payments= $3,200
Wife's car= $540
Tom's car = $395
Total = $4,135
Monthly income:
Retirement income = $2,500
Social Security income = $1,200
Rental income = $1,680
Total = $5,380
Debt to income ratio:
$4,135/$5,380
= 0.77 X 100
= 77%
The following are the expected one-year T-bill rates for the next
four years: 3%, 4%, 5% and 6%. According to the basic model of the expectations hypothesis, what would you expect the rate for three-year securities to be?
Answer:
4%
Explanation:
The computation of rate for three-year securities is shown below:-
Expected Rate for three year securities = (First year + Second year + Third year) + Rate for three year
= (3% + 4% + 5%) ÷ 3
= 12% ÷ 3
= 4%
Therefore for computing the rate for three-year securities we simply applied the above formula.
Since we have to find out the three year securities rate so we considered only three year T bill rates

The question is incomplete! Complete question along with answer and step by step explanation is provided below.
Question:
Suppose both Adrian and Clemens invest $10,000 in a mutual fund.
Lets think of it another way so that we can see the impact of compounding on this investment. For simplicity's sake, we will assume that Adrian's rate of return is effectively 5.7% annually (7% - 1.3% fee) and Clemens's rate of return is effectively 6.8% annually (7% - 0.2% fee).
7. How much will Adrian have if he allows his investment to remain in the mutual fund for 10 years?
8. How much will Clemens have if he allows his investment to remain in the index fund for 10 years?
9. How much more value does Clemens's investment generate than Adrian's in 10 years' time?
10. What about over 40 years time?
Answer:
7. Adrian's amount = $17,408
8. Clemens's amount = $19,306
9. Difference in amount after 10 years = $1,898
10. Difference in amount after 40 years = $47,114
Explanation:
7. How much will Adrian have if he allows his investment to remain in the mutual fund for 10 years?
Adrian will have a amount given by
[tex]A = P\times(1+r)^{n}[/tex]
Where P is the invested amount, r is the annual rate of return and n is the number of years.
Here P = 10,000, r = 0.057, n = 10
[tex]A = 10,000\times(1+0.057)^{10}\\\\A = 10,000\times 1.7408\\\\A = \$17,408[/tex]
8. How much will Clemens have if he allows his investment to remain in the index fund for 10 years?
Clemens will have a amount given by
[tex]A = P\times(1+r)^{n}[/tex]
Here P = 10,000, r = 0.068, n = 10
[tex]A = 10,000\times(1+0.068)^{10}\\\\A = 10,000\times 1.9306\\\\A = \$19,306[/tex]
9. How much more value does Clemens's investment generate than Adrian's in 10 years' time?
[tex]\text {Difference} = \$19,306 - \$17,408 = \$1,898[/tex]
Therefore, Clemens's investment generate $1,898 more as compared to Adrian's in 10 years time period.
10. What about over 40 years time ?
Adrian's amount:
Here P = 10,000, r = 0.057, n = 40
[tex]A = 10,000\times(1+0.057)^{40}\\\\A = 10,000\times 9.1833\\\\A = \$91,833[/tex]
Clemens's amount:
Here P = 10,000, r = 0.068, n = 40
[tex]A = 10,000\times(1+0.068)^{40}\\\\A = 10,000\times 13.8947\\\\A = \$138,947[/tex]
[tex]\text {Difference} = \$138,947 - \$91,833 = \$47,114[/tex]
Therefore, Clemens's investment generate $47,114 more as compared to Adrian's in 40 years time period.

D. Current assets minus merchandise inventory
Working capital is a measure of a company's short-term financial health and it is defined as current assets minus current liabilities. This calculation shows how much the company has to cover its short-term liabilities, which is critical for maintaining ongoing operations.
Explanation:Working capital is an essential measure of a company's short-term financial health and operational efficiency. It is best described as current assets minus current liabilities. This calculation shows how much the company has on hand to cover its short-term liabilities and obligations, which is critical for maintaining ongoing business operations.
For instance, if a company has $50,000 in current assets and $30,000 in current liabilities, the working capital is $20,000. This means that after paying off its short-term liabilities, the company will have $20,000 left for running its daily operations.

It's the funds available to cover day-to-day operations and pay off short-term debts. The other options mentioned do not accurately define working capital.
Explanation:The term 'working capital' in the field of finance and accounting refers to the difference between a company's current assets and current liabilities. This calculation is crucial as it helps determine the short-term financial health of an entity. In simple terms, working capital is the amount of money a company has available to cover its day-to-day operations, such as paying off short-term debts and purchasing inventory.
For instance, if a company's current assets amount to $500,000 and its current liabilities total $300,000, the working capital is $500,000 - $300,000, which equals $200,000. A positive working capital indicates that the company has enough assets to cover its short-term liabilities. On the other hand, a negative working capital could suggest potential financial distress.

about 68% of brand x’s batteries have a lifespan between ____ and ____ hours. about 68% of brand y’s batteries have a lifespan between _____ and _____ hours. the life span of brand _____’s battery is more likely to be consistently close to the mean.
Answer:
about 68% of brand x’s batteries have a lifespan between 95.2 hours and 108.8 hours. about 68% of brand y’s batteries have a lifespan between 98.6 hours and 101.4 hours. the life span of brand y’s battery is more likely to be consistently close to the mean.
Explanation:
According to the empirical rule (68–95–99.7 rule) for a normal distribution, 68% of the data falls within the first standard deviation (μ ± σ).
Given for brand x, mean (μ) = 102 hours and standard deviation (σ) = 6.8 hours.
first standard deviation (μ ± σ) = 102 ± 6.8 = (95.2, 108.8)
about 68% of brand x’s batteries have a lifespan between 95.2 hours and 108.8 hours.
Given for brand y, mean (μ) = 100 hours and standard deviation (σ) = 1.4 hours.
first standard deviation (μ ± σ) = 100 ± 1.4 = (98.6, 101.4)
about 68% of brand x’s batteries have a lifespan between 98.6 hours and 101.4 hours.
Since the standard deviation of brand y is smaller than that of brand x, brand y battery is more likely to be consistently close to the mean
The lifespan of about 68% of brand x’s batteries is between 95.2 hours and 108.8 hours, and The lifespan of about 68% of brand y’s batteries is between 98.6 hours and 101.4 hours. The life span of brand y’s battery is more likely to be consistently close to the mean.

Individuals who are purchasing car insurance are likely to be aware of certain risk factors related to their driving habits or vehicle that are not easily accessible to insurers, such as their propensity for high-risk driving. Moreover, a person who is seeking life insurance might have more intimate knowledge of their family's health history than what an insurer could obtain without undertaking an expensive investigation.
Regarding vehicle insurance, apart from the protection it offers against large out-of-pocket expenses in the event of an accident, it's essential to consider how the car's safety rating, the driver's history, and in the case of used vehicles, the vehicle's history could affect insurance rates. Insurance premiums may be paid monthly, quarterly, or bi-annually, and this is a recurrent expense that continues even after the vehicle is paid off. Age also plays a critical role in determining insurance rates, with younger and less experienced drivers often paying higher rates.
A professor of statistics claimed that the average amount of money a typical college
student spends per day during social distancing at home is over $70. Based upon
previous research, the population standard deviation is estimated to be $17.32. The
professor surveys 35 students and finds that the mean spending is $67.57. Is there
evidence that the average amount spent by students is less than $70? State hypotheses,
calculated value, critical value at a = 0.1
the professor wants to know wether the sample mean 67.57 is high enough.
Answer:
We fail to reject the Null hypotheses that the average amount of money a typical college student spends per day is less than $70.
Explanation:
A professor of statistics claimed that the average amount of money a typical college student spends per day during social distancing at home is over $70.
Based upon previous research, the population standard deviation is estimated to be $17.32.
The professor surveys 35 students and finds that the mean spending is $67.57.
Is there evidence that the average amount spent by students is less than $70?
For the given problem the Null hypotheses is that the average amount of money a typical college student spends per day is less than $70.
[tex]H_0= \mu <70[/tex]
For the given problem the Alternate hypotheses is that the average amount of money a typical college student spends per day is over $70.
[tex]H_1= \mu >70[/tex]
The test statistic is given by
[tex]z = \frac{\bar{X}-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex]
Where X_bar is the sample mean spending that is $67.57, μ is the average population spending that is $70, σ is the standard deviation that is 17.32 and n is the sample size that is 35.
[tex]z = \frac{67.57-70}{\frac{17.32}{\sqrt{35} } }\\\\z = \frac{-2.43}{ 2.927}\\\\z = -0.83[/tex]
The p-value corresponding to the z-score of -0.83 at significance level 0.10 is found to be
p-value = 0.2036
Since 0.2036 > 0.10
We fail to reject the Null hypotheses that the average amount of money a typical college student spends per day is less than $70.
