The stockout probability is extremely small, as the z-score of 7.22 corresponds to a very high demand compared to the available stock.

What is probability?

Probability is a fundamental concept in mathematics and statistics that quantifies the likelihood of an event occurring. It represents a numerical measure between 0 and 1, where 0 indicates an event is impossible, and 1 denotes the event is certain to happen.

Given:

Mean demand per period\((\(\mu\))\) = 50

Standard deviation of demand per period\((\(\sigma\))\)= 6

Order-up-to level \((\(S\)) = 225\)

Lead time \((\(L\)) = 3 periods\)

We can calculate the demand during the lead time as follows:

Mean demand during the lead time: \(\(\mu_L = \mu \times L\)\)

Standard deviation of demand during the lead time:\(\(\sigma_L = \sigma \times \sqrt{L}\)\)

Substituting the given values, we have:

\(\(\mu_L = 50 \times 3 = 150\)\(\sigma_L = 6 \times \sqrt{3} \approx 10.39\)\)

To calculate the stockout probability, we need to compare the demand during the lead time to the available stock. Since the demand follows a Normal distribution, we can use the z-score formula:

\(\(z = \frac{S - \mu_L}{\sigma_L}\)\)

where \(S\) is the order-up-to level.

Substituting the values, we have:

\(\(z = \frac{225 - 150}{10.39} \approx 7.22\)\)

We can then use a standard Normal distribution table or a statistical software to find the probability of a z-score being greater than 7.22. The stockout probability is equal to this probability.

The mode is the most appropriate measure of center to represent the data in the graph because it reflects the most common value(s) observed in the dataset. In this case, the mode is 3.

The most appropriate measure of center to represent the data in the given line plot is the mode.

The mode is the value or values that occur most frequently in a dataset. In this case, we can observe the frequencies of the data points on the line plot:

There is one dot above 2, 4, 8, and 9.

There are two dots above 6 and 7.

There are three dots above 3.

Based on this information, the mode(s) of the dataset would be the values that have the highest frequency. In this case, the mode is 3 because it appears most frequently with a frequency of three. The other data points have frequencies of one or two.

The mode is particularly appropriate in this scenario because it represents the most common or frequently occurring value(s) in the dataset. It is useful for identifying the central tendency when the data is discrete and there are distinct peaks or clusters.

While the median and mean are also measures of center, they may not be the most appropriate in this case. The median represents the middle value and is useful when the data is ordered. However, the given line plot does not provide an ordered arrangement of the data points. The mean, on the other hand, can be affected by outliers and extreme values, which may not accurately represent the central tendency of the dataset in this scenario.

Therefore, the mode is the most appropriate measure of center to represent the data in the graph because it reflects the most common value(s) observed in the dataset. In this case, the mode is 3.

The expected value of the warranty for Emily's printer is $1.50, indicating a potential gain. Whether she should purchase it depends on personal circumstances and the value she places on peace of mind and free replacement.

To calculate the expected value of the warranty, we need to consider the cost of the warranty and the probability of the printer breaking.

The cost of the warranty is $25, and the probability of the printer breaking is 6% or 0.06.

The expected value is calculated by multiplying the cost by the probability of the event occurring. In this case, it is:

Expected Value = Cost of Warranty * Probability of Printer Breaking

Expected Value = $25 * 0.06

Expected Value = $1.50

Therefore, the expected value of the warranty is $1.50.

Now, should Emily purchase the warranty?

If the expected value of the warranty is positive, it means that the potential benefit outweighs the cost, making it a favorable option. In this case, since the expected value is $1.50, which is positive, Emily can expect to gain $1.50 on average by purchasing the warranty.

However, it's important to consider personal circumstances and risk tolerance. If Emily is confident in the printer's quality or already has an alternative plan for potential repairs, she may choose not to purchase the warranty. On the other hand, if she values the peace of mind and wants the assurance of a free replacement, she may decide to purchase the warranty.

Ultimately, the decision to purchase the warranty depends on Emily's individual preferences and circumstances.

Answer:

We know that in the box there are:

4 twix

3 kit-kat

Then the total number of candy in the box is:

4 +3 = 7

a)

Here we want to find the probability that we draw two twix.

All the candy has the same probability of being drawn from the box.

So, the probability of getting a twix in the first drawn, is equal to the quotient between the number of twix and the total number of candy in the box, this is:

p = 4/7

Now for the second draw, we do the same, but because we have already drawn one twix before, now the number of twix in the box is 3, and the total number of candy in the box is 6.

this time the probability is:

q = 3/6 = 1/2

The joint probability is the product of the individual probabilities, so here we have

P = p*q = (4/7)*(1/2) =  2/7

b) same reasoning than in the previous case:

For the first bar, the probability is:

p = 3/7

for the second bar, the probability is:

q = 2/6 = 1/3

The joint probability is:

P = p*q = (3/7)*(1/3) = 1/7

c) Suppose that first we draw a twix.

The probability we already know that is:

p = 4/7

Now we want another type, so we need to draw a kit-kat, the probability will be equal to the quotient between the remaining kit-kat bars (3) and the total number of candy in the box (6)

q = 3/6

The joint probability is:

P = p*q = (4/7)*(3/6) = 2/7

But, we also have the case where we first draw a kit-kat and after a twix, so we have a permutation of two, then the probability in this case is:

Probability = 2*P = 2*2/7 = 4/7

The rate of change of the cube's surface area when its edges are 70mm long is -0.014 mm/s.

This indicates that the surface area is decreasing at a rate of 0.014 \(mm^2/s.\)

To find the rate of change of the cube's surface area when its edges are 70mm long, we can use the formulas for the volume and surface area of a cube.

The volume of a cube is given by\(V = s^3,\)  where s is the length of the cube's edges.

In this case, the volume is decreasing at a rate of 210mm^3/s.

Differentiating both sides of the equation with respect to time, we get \(dV/dt = 3s^2 ds/dt,\)

where dV/dt represents the rate of change of volume and ds/dt represents the rate of change of the edge length.

Since we are given that \(dV/dt = -210mm^3/s\) and s = 70mm, we can substitute these values into the equation and solve for ds/dt.

\(-210 = 3(70^2) ds/dt\)

-210 = 3(4900) ds/dt

\(ds/dt = -210 / (3 \times 4900)\)

ds/dt = -0.014 mm/s

Therefore, the rate of change of the cube's surface area when its edges are 70mm long is -0.014 mm/s.

This indicates that the surface area is decreasing at a rate of 0.014 \(mm^2/s.\)

Since both Kyle and Caleb scored 1 standard deviation above their respective class means, we can conclude that their performances were relatively equal.

A standard deviation is a measure of how far apart the data is from the mean.

A low standard deviation indicates that data is clustered around the mean, whereas a high standard deviation indicates that data is more spread out.

To determine whose performance was better relative to their class, we need to calculate their z-scores, which tell us how many standard deviations a particular score is from the mean.

For Kyle in Class A:

z-score = (82 - 77) / 5 = 1

This means that Kyle's score is 1 standard deviation above the mean for his class.

For Caleb in Class B:

z-score = (87 - 80) / 7 = 1

This means that Caleb's score is also 1 standard deviation above the mean for his class.

Thus, we can conclude that Kyle and Caleb's performances were comparable because they both scored one standard deviation above their respective class means.

The probability that the sample proportion will be less than 0.1 is 1.0000.

To find the probability that the sample proportion will be less than 0.1 when a direct mail company samples 276 people and the true proportion is 0.06, we can use the normal approximation for the binomial distribution. Here are the steps:

1. Calculate the mean (μ) and standard deviation (σ) of the binomial distribution.
  μ = n * p = 276 * 0.06 = 16.56
  σ = √(n * p * (1 - p)) = √(276 * 0.06 * 0.94) ≈ 3.94

2. Convert the sample proportion to a z-score.
  z = (x - μ) / σ = (0.1 * 276 - 16.56) / 3.94 ≈ 7.01

3. Use a z-table or calculator to find the probability corresponding to this z-score. Since we want the probability that the sample proportion is less than 0.1, we look up the area to the left of the z-score.
  P(z < 7.01) ≈ 1.0000 (almost certain)

Talking about probabilities, the probability of events ranges from 0 to 1. With 1 being the highest value the probability of an event can take while 0 is the lowest value the probability of an event can take. The probability of an event can neither be negative, nor greater than 1. It lies between 0 and 1

Now, the closer a probability is to 1, the greater the likelihood of that particular event happening. Events having probabilities closer to 1 are more likely to occur than those farther away from 1 or closer to zero.

In this question, 0.9 is a greater value compared to 0.8. Thus, an event of probability 0.9 is more likely to happen compared with an event with probability of 0.8

In other words, an event with probability 0.8 is less likely to occur compared with an event with a probability value of 0.9
