Yoonie is a personnel manager in a large corporation. each month she must review 16 of the employees. from past experience, she has found that the reviews take her approximately four hours each to do with a population standard deviation of 1.2 hours. let χ be the random variable representing the time it takes her to complete one review. assume χ is normally distributed. let 9 o be the random variable representing the mean time to complete the 16 reviews. assume that the 16 reviews represent a random set of reviews. 1. what is the mean, standard deviation, and sample size? 2. complete the distributions.
a. x ~ _____(_____,_____)
b. 9 o ~ _____(_____,_____)
Answer:
Sample size is 16
Mean 4
Standard deviation of the sample is 0.3.
Explanation
The Central Limit Theorem estabilishes that, for a random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], a large sample size can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\frac{\sigma}{\sqrt{n}}[/tex].
In this problem, we have that:
The population has a mean of four hours, with a standard deviation of 1.2 hours. The sample is the 16 of the employees.
So
The sample size is 16, so [tex]n = 16[/tex]
The mean of the sample is the same as the population mean, so [tex]\mu = 4[/tex].
The standard deviation of the sample is [tex]s = \frac{\sigma}{\sqrt{n}} = \frac{1.2}{4} = 0.3[/tex]

Voltage industries, a calendar-year company, purchases equipment for $85,000 on january 2nd, 2017. the equipment's expected useful life is five years, and the expected salvage value of the equipment is $5,000. what is the book value of the equipment on december 31st, 2018, if voltage uses the double-declining-balance method?
a.$34,000
b.$51,000
c.$54,400
d.$30,600
By using the double-declining-balance method of depreciation, the book value of the equipment on December 31, 2018, is calculated to be $30,600.
Explanation:The double-declining-balance method is a form of accelerated depreciation method where an asset loses its value faster in the early years of its lifespan. The formula involves doubling the straight-line depreciation rate. In this case, the book value of the equipment is calculated as follows:
Determine depreciation expense for the first year by taking the cost of the equipment, $85,000, and multiply it by the double of the straight-line rate (1 / 5 years = 20%, so 20% x 2 = 40%).Subtract this depreciation expense from the cost of the equipment, which gives the book value at the end of the first year: $85,000 - ($85,000 x 40%) = $51,000.For the second year (2018), repeat the process, but use the book value at the end of the first year as the new basis: $51,000 - ($51,000 x 40%) = $30,600.So the book value on December 31, 2018, is $30,600.

Type i rooms do not have high-speed wireless internet access and are not available for the business rental class. round tree's management makes a forecast of the demand by rental class for each night in the future. a linear programming model developed to maximize profit is used to determine how many reservations to accept for each rental class. the demand forecast for a particular night is 120 rentals in the super saver class, 65 in the deluxe class, and 50 in the business class. round tree has 100 type i rooms and 110 type ii rooms.
Final answer:
Round Tree's management uses a linear programming model to determine how many reservations to accept for each rental class in order to maximize profit.
Explanation:
The linear programming model developed by Round Tree's management is used to determine how many reservations to accept for each rental class in order to maximize profit. However, Type I rooms do not have high-speed wireless internet access and are not available for the business rental class. Therefore, the demand forecast for the Type I rooms is not considered in the model.
The demand forecast for a particular night is 120 rentals in the Super Saver class, 65 rentals in the Deluxe class, and 50 rentals in the Business class. Round Tree has 100 Type I rooms and 110 Type II rooms.
To determine how many reservations to accept for each rental class, Round Tree's management would need to consider the availability of Type II rooms and the demand forecast for each rental class. They would then allocate the available rooms based on the demand to maximize profit.

A _____ is a strategy for expanding capacity that waits until demand has increased to a point where additional capacity is necessary.
a. capacity lead strategy
b. capacity reduction strategy
c. capacity match strategy
d. capacity lag strategy
The strategy that waits to expand capacity until after demand has increased to a point where more capacity is required is called a capacity lag strategy.
Explanation:In response to the question, the strategy for expanding capacity that waits until demand has increased to a point where additional capacity is necessary is known as a capacity lag strategy. This strategy aligns with entrepreneurship and business growth, whereby organisations only increase their production abilities when there is a high demand for their product or service. This is to prevent unnecessary spending on production when there isn't enough demand to make that production profitable.

A capacity lag strategy is a business approach where a company expands its production capacity only when there is a clear increase in demand, as opposed to investing ahead of time.
The strategy for expanding capacity that waits until demand has increased to a point where additional capacity is necessary is known as a capacity lag strategy. Unlike an over-investment strategy, which involves creating excess capacity ahead of time as a signal or deterrent to potential competitors, a capacity lag strategy does not incur the cost of expanding production until it is justified by increased demand. This strategy is often in contrast to capacity lead strategies where investments are made in anticipation of future demand. Given these considerations, the correct answer is: d. capacity lag strategy.

A loan officer will use _____ to determine if you will be approved for a loan.
A. the four Cs of lending
B. the formula, P x (J / (1 – (1 + J)N))
C. debt-to-income ratio
D. a lease
A loan officer uses the four Cs of lending and the borrower's debt-to-income ratio to determine loan approval. Factors like income, credit history, and the potential for collateral or a cosigner are also considered.
A loan officer will use the four Cs of lending, which include character, capacity, capital, and collateral, and the debt-to-income ratio to determine if you will be approved for a loan. The debt-to-income ratio is calculated by dividing your monthly debt payments by your gross monthly income, which helps lenders measure your ability to manage loan payments. For example, a 43 percent debt-to-income ratio is typically the highest a borrower can have to qualify for a Qualified Mortgage, as higher ratios are associated with an increased likelihood of payment difficulties.
Additionally, lenders in the financial capital market require borrowers to fill out income source forms and conduct credit checks, sometimes requiring cosigners or collateral that the bank could seize and sell if the loan is not repaid. Therefore, multiple factors determine loan approval, not just a single formula or variable.

Suppose 1 in 200 pilots flying space-x aircraft dies each year while only 1 in 500 pilots flying subspace gliders dies each year. moreover, the average salary of space-x pilots is $115,000, while the average salary of subspace glider pilots is $109,000. given this information, what is the implied statistical value of a life of a pilot?
a. $120,000
b. $1,200,000
c. $2,000,000
d. $6,000
e. $480,000
The implied statistical value of a pilot's life given the data provided is $7,500,000, which is not included in the options provided in the question.
Explanation:The salary difference is $115,000 - $109,000 = $6,000. Space-X pilots have a death rate of 1 in 200, while Subspace glider pilots have a death rate of 1 in 500, the difference in risk is 1/500 - 1/200 = 1/1,250. Thus, the implied statistical value of a pilot's life is $6,000 * 1,250 = $7,500,000. None of the options a, b, c, d, and e is correct.The question asks about the implied statistical value of a life of a pilot, given certain death rates for different types of pilots and their respective average salaries. This type of calculation is often used in economics and insurance industries to establish how much value is ascribed to a single human life, based on various statistical and financial factors.To find the implied statistical value, we need to understand how many more dollars a Space-X pilot is paid compared to a Subspace glider pilot, divided by the additional risk they bear. The salary difference is $115,000 - $109,000 = $6,000. Space-X pilots have a death rate of 1 in 200, while Subspace glider pilots have a death rate of 1 in 500, the difference in risk is 1/500 - 1/200 = 1/1,250. Thus, the implied statistical value of a pilot's life is $6,000 * 1,250 = $7,500,000. None of the options a, b, c, d, and e is correct.
