Answer:

11.55% probability that the purchase was made with a mobile device and was from Amazon.

Step-by-step explanation:

We have these following probabilities:

21% probability that a Cyber Monday shopper used their mobile device to make a purchase.

55% probability that a purchase made with a mobile device is from Amazon.

What is the probability that the purchase was made with a mobile device and was from Amazon."

55% of 21%

So

P = 0.21*0.55 = 0.1155

11.55% probability that the purchase was made with a mobile device and was from Amazon.

The residual value is the difference between the actual and predicted values. Hence, the residual activity at a temperature of 69°F will be −2484.95

The equation of the Least Square Regression Line is given as :

The predicted amount of activity, y at a temperature of 69°F will be :

y = 152.1 + 37.65(69)

y = 2749.95

The actual amount of activity at a temperature of 69°F is 265

The residual activity at 69°F temperature can be calculated thus :

Residual = Actual - Predicted

Residual = 265 - 2749.95 = −2484.95

Therefore, the residual activity at 69°F is −2484.95

Required Information:

Probability of 1 or more donors of "O" blood group = ?

Answer:

P( x ≥ 1 ) = 0.710

Step-by-step explanation:

We are given the probability that a donor has type "O" blood group.

We want to find out the probability of having 1 or more donors who has type "O" blood group out of 20 donors.

P( x ≥ 1 ) = 1 - P( x = 0)

So we will first find the probability that none of the donors has type "O" blood group then we will subtract that from 1 to get the probability of having 1 or more donors with "O" blood group.

P( x = 0) = (p⁰)(1 - p)²⁰

P( x = 0) = (0.06⁰)(1 - 0.06)²⁰

P( x = 0) = (1)(0.94)²⁰

P( x = 0) = 0.290

So the probability of having 1 or more donors with "O" blood group is

P( x ≥ 1 ) = 1 - P( x = 0)

P( x ≥ 1 ) = 1 - 0.290

P( x ≥ 1 ) = 0.710

P( x ≥ 1 ) = 71%

Therefore, the correct answer is D. 0.710

Final answer:

The probability that 1 or more donors have type O blood is approximately 0.370.

Explanation:

The probability that 1 or more donors have type O blood can be found using the complement rule. The complement of the event that 0 donors have type O blood is the event that 1 or more donors have type O blood.

The probability that a donor has type O blood is 0.06. The probability that a donor does not have type O blood is 1 - 0.06 = 0.94. Let's calculate the complement probability:

P(1 or more donors have type O blood) = 1 - P(0 donors have type O blood)

= 1 - (0.94)^{20} (since the donors are independent)

Using a calculator, we get P(1 or more donors have type O blood) ≈ 0.370

The probability distribution function of X, filled in:

X    P(X)

0    1/8

1     3/8  

2    3/8

3     1/8

Possible outcomes: There are 2^3 = 8 possible outcomes when a fair coin is tossed 3 times (HHH, HHT, HTH, THH, HTT, THT, TTH, TTT).

Counting tails: We count the number of tails in each outcome to determine the values of X.

Probability of each X: We calculate the probability of each value of X by counting the outcomes that correspond to that value and dividing by the total number of outcomes (8).

Detailed breakdown:

X = 0: Only one outcome has 0 tails (HHH), so P(X=0) = 1/8.

X = 1: Three outcomes have 1 tail (HHT, HTH, THH), so P(X=1) = 3/8.

X = 2: Three outcomes have 2 tails (HTT, THT, TTH), so P(X=2) = 3/8.

X = 3: Only one outcome has 3 tails (TTT), so P(X=3) = 1/8.

Answer:

36.32% probability that the claim amount under liability insurance exceeds the claim amount under collision insurance.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Two variables:

X1 and X2, probability X1 exceeds X2

[tex]\mu(X_{1} - X_{2}) = \mu_{X_{1}} - \mu_{X_{2}}[/tex]

[tex]\sigma^{2}(X_{1} - X_{2}) = \sigma_{X_{1}}^{2} +  \sigma_{X_{2}}^{2}[/tex]

In this problem, we have:

X1: Liability insurance:

So [tex]\mu_{X_{1}} = 9000, \sigma_{X_{1}} = 2000[/tex]

X2: Collusion insurance:

So [tex]\mu_{X_{2}} = 10000, \sigma_{X_{2}} = 2000[/tex]

Then

[tex]\mu(X_{1} - X_{2}) = \mu_{X_{1}} - \mu_{X_{2}} = 9000 - 10000 = -1000[/tex]

[tex]\sigma^{2}(X_{1} - X_{2}) = 2000^{2} + 2000^{2} = 8000000[/tex]

[tex]\sigma = \sqrt{8000000} = 2828.43[/tex]

Assuming independence, find the probability that the claim amount under liability insurance exceeds the claim amount under collision insurance.

This is [tex]P(X_{1} - X_{2} > 0)[/tex], which is 1 subtracted by the pvalue of Z when X = 0. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0 - (-1000)}{2828.43}[/tex]

[tex]Z = 0.35[/tex]

[tex]Z = 0.35[/tex] has a pvalue of 0.6368

1 - 0.6368 = 0.3632

36.32% probability that the claim amount under liability insurance exceeds the claim amount under collision insurance.

Step-by-step explanation:

using the Convolution theorem to find the inverse of :

     [tex]\frac{5}{s^{3}(s^{2}+25 ) }[/tex]

   [tex]L^{-1}[/tex]  [tex]\frac{5}{s^{3}(s^{2}+25 ) }[/tex] = [tex]\frac{1}{s^{3} }[/tex] × [tex]\frac{5}{s^{2}+25}[/tex]

we know from derivation that

Sin(at) =  [tex]\frac{a}{s^{2}+a^{2} }[/tex]

Hence: [tex]\frac{5}{s^{2}+25}[/tex]  = Sin5t

Also:  [tex]L^{-1}[/tex] [tex]\frac{n!}{s^{n+1} }[/tex] = [tex]t^{n}[/tex]

     [tex]L^{-1}[/tex]  [tex]\frac{1}{s^{3} }[/tex] = [tex]\frac{1}{2}[/tex] [tex]L^{-1}[/tex] ([tex]\frac{2!}{s^{3} }[/tex])

 = [tex]\frac{1}{2}[/tex][tex]t^{2}[/tex]

therefore [tex]L^{-1}[/tex]  [tex]\frac{5}{s^{3}(s^{2}+25 ) }[/tex] = [tex]\frac{1}{2}[/tex][tex]t^{2}Sin5t[/tex]

Probability of finding a person who tested negative = ?

Answer:

P( x = 1 ) = 0.000315 = 0.0315%

Step-by-step explanation:

Let the probability of success is denoted by those who test negative,

p = 33/39

p = 0.85

Then the probability of failure is denoted by those who test positive,

q = 1 - p = 1 - 0.15 = 0.85

We want to find out the probability of finding a random person who test negative.

P( x = 1 ) = (p³⁹⁻¹)(1 - p)¹

P( x = 1 ) = (0.85³⁹⁻¹)(1 - 0.15)¹

P( x = 1 ) = 0.0021*0.15

P( x = 1 ) = 0.000315

Therefore, the Probability of finding a person who tested negative is 0.0315%

The initial expectation is that 20% of the M&Ms in a bag would be orange. However, the occurrence of 25.5% orange M&Ms in a bag can be considered surprising but doesn't negate the initial percentage due to statistical sampling variability.

This question is dealing with the concept of statistical sampling and proportions. Given that the M&M’s website states that 20% of milk chocolate M&M’s are orange, we would expect, on average, that 20% or 11 (0.20 * 55) of the M&M’s in a small bag of 55 M&M’s to be orange. However, in this instance, we observe that 25.5% (or 14 of the 55) of the M&M’s are orange.

This result might be surprising because it is more than the average expectation of 20%. But it's important to remember the concept of sampling variability. Even though we expect 20%, the actual results can vary from this expectation due to random chance.

In conclusion, this result can be considered surprising because we have got a higher percentage of orange candies than expected, but it does not necessarily prove that the initial assertion of 20% orange M&M’s is incorrect due to the inherent variability in statistical sampling.

The observed result of 25.5% orange candies per bag is surprising given the stated 20% proportion. However, due to sampling variability, it falls within one standard deviation from the mean, indicating it's a possible result in a sample.

The conclusion based on your provided information would be that this result is surprising because it is unlikely to select a sample with 25.5% or more orange candies if only 20% of milk chocolate M&M's are orange. This observation is compared to the expected proportion of 20%, i.e., the stated percentage of orange M&M's as per the website information.

To calculate how surprising this outcome is, we can use the concept of standard deviation. Based on the binominal distribution, the standard deviation (σ) is calculated as √npq, where n is the number of trials (in this case, the number of candies per bag, 55), p is the probability of success (the expected proportion of orange candies, 0.20), and q is the probability of failure (1-p).

Applying these values, σ = √(55)(0.20)(0.80), we get σ ≈ 4.7. Therefore, observing 14 orange candies is about one standard deviation above the expected value (11 candies, or 20% of 55). Although that might seem like a significant deviation, in a normal distribution about 68% of the data falls within one standard deviation of the mean. So while it is surprising, it is still a possible variation to have 25.5% or more orange candies in a single bag due to sampling variability.

Answer:

33,554,432 sectors

Step-by-step explanation:

-We first convert both sizes to a uniform measure(both to be in bytes or gigabytes).

-We convert the drive size into Bytes:

[tex]1GB=1,073,741,824 \ Bytes\\\\\therefore 16GB=16\times1,073,741,824=1.717986918\times10^{10}\ Bytes[/tex]

#We then divide the Drive size by the sector size to get the number of sectors.

-Let X be the number of sectors:

[tex]X=\frac{Drive \ Size}{Sector \ Size}\\\\=\frac{1.717986918\times10^{10}}{512}\\\\=33,554,432[/tex]

Hence, the disk has 33,554,432 sectors.

To calculate the number of sectors in a 16GB disk, you first convert the disk size from GB to bytes. Then, you divide the total bytes by the size in bytes of one sector. So, a 16GB disk has 33,554,432 sectors.

The disk size is provided in gigabytes (GB), but first, we need to convert it into bytes, as sectors are measured in bytes. There are 1,073,741,824 bytes in 1 GB. Therefore, a 16 GB disk has 16 * 1,073,741,824 = 17,179,869,184 bytes.

Since each sector is 512 bytes, we can find the number of sectors by dividing the total number of bytes by the size of one sector: 17,179,869,184 / 512 = 33,554,432 sectors.

A. There is enough evidence that p < 0.05 that the mean distance between ball one and two as measured by his computed tomography machine is greater than 16.02mm.

Step-by-step explanation:

n= 5

x bar= 16.02

Standard Error= 0.02236

NB:

The null hypothesis is referred to as a characteristic arithmetic theory that gives a statement that suggests that no statistical relationship and significance exists in a set of given observed variables between two sets of observed data and also, measured phenomena. The hypotheses play a crucial role in testing the significance of differences in experiments and between observations. H o represents the null hypothesis of no difference.

The alternative hypothesis is generally represented as H1. It makes a statement that suggests a potential result or an outcome that a researcher may expect.

Standard error measures how far the sample mean of the data is most likely to be from the true population mean.

We want to test the null and alternative hypothesis

H o : μ = 15.96 vs H1 : μ > 15.96

1. Test statistics

Z= xbar - μ / Standard error

Z= 16.02 - 15.96 / 0.002236

Z= 2.6834

Answer: 176 degrees and 4 degrees.

Step-by-step explanation: To find the measure of the angles, all you have to do is create an equation. Let's call the supplementary angle x and the other angle 44x, because the other angle is 44*the supplementary angle. Now, we structure the equation 44x + x = 180. The reason we say the sum of the angles is 180 is because any angle plus its supplementary angle equals 180 degrees. From there it's just algebra:

44x + x = 180

45x = 180

x = 180/45

x = 4

We can check our work by substituting x for 4 in the equation:

44*4 + 4 = 180

174 + 4 = 180

180 = 180

Thus, the first angle is 176 degrees and the second is 4 degrees.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the annual precipitation of a population, and for this case we know the distribution for X is given by:
