Step-by-step explanation:

Therefore, the probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 is 0.25, or 25%.

The probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 can be found using the formula:

P(event) = number of favorable outcomes / total number of possible outcomes

In this case, the number of favorable outcomes is 3, since there are 3 preparation stations that we are interested in (6, 7, and 8). The total number of possible outcomes is 12, since there are 12 preparation stations in total.

So, the probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 is:

P(event) = 3 / 12

P(event) = 0.25

Therefore, the probability that a randomly chosen product was prepared on preparation stations 6, 7, and 8 is 0.25, or 25%.

The given problem is asking for a test to see if the sample mean is significantly different from 85 at the 0.05 level. To solve the problem, we can use the following formula:$$t = \frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}}}$$where$\bar{x}$ = sample mean$\mu$ = population mean$s$ = sample standard deviation$n

$ = sample sizeTo calculate the t-value, we need to calculate the sample mean and the sample standard deviation. The sample mean is calculated as follows:$$\bar{x} = \frac{\sum_{i=1}^{n} x_i}{n}$$where $x_i$ is the score of the $i$th student and $n$ is the sample size.

Using the given data, we get:$$\bar

{x} = \frac{78+89+67+85+90+83+81+79}{8}

= 81.125$$The sample standard deviation is calculated as follows:$$

s = \sqrt{\frac{\sum_{i=1}^{n} (x_i - \bar{x})^2}{n-1}}$$Using the given data, we get:$$

s = \sqrt{\frac{(78-81.125)^2+(89-81.125)^2+(67-81.125)^2+(85-81.125)^2+(90-81.125)^2+(83-81.125)^2+(81-81.125)^2+(79-81.125)^2}{8-1}}

= 7.791$$Now we can calculate the t-value as follows:$$

Answer:

x=3 and y=-2

Step-by-step explanation:

2x - 3y = 6

2x - 3(0) = 6

2x = 6

divide both sides by 2

x = 3

2x - 3y = 6

The scenario described above illustrates the Service Recovery Paradox, where a customer's satisfaction can actually increase after experiencing a service failure and receiving effective recovery efforts.

Dr. Amarkant Tripathi faced a delay and inconvenience with his suit order from B N Rao suits, but the store manager went above and beyond to rectify the situation, ultimately leading to Dr. Tripathi's increased satisfaction and loyalty.

The Service Recovery Paradox occurs when a customer's satisfaction and loyalty increase even after encountering a service failure. In the given context, Dr. Tripathi experienced a delay and fitting issue with his suit order. However, the store manager took prompt action to resolve the problem and ensure Dr. Tripathi's satisfaction.
Despite initial setbacks, the store manager exhibited proactive service recovery efforts. He communicated with Dr. Tripathi, apologized sincerely, and made efforts to rectify the situation promptly. The manager's willingness to listen, understand, and address the customer's concerns played a crucial role.
Furthermore, the store manager's personal involvement, contacting Dr. Tripathi's home, explaining the situation to his daughter, and arranging for the suit to be taken to the Domlur branch for repairs and express delivery showcased a high level of customer service and dedication to resolving the issue.
These service recovery efforts exceeded Dr. Tripathi's expectations and demonstrated B N Rao suits' commitment to customer satisfaction. As a result, when Dr. Tripathi received the suit, along with the apology note and additional handkerchiefs, he felt not only satisfied with the resolution but also impressed by the store's efforts to understand his needs and deliver a superior service experience.
The Service Recovery Paradox, in this case, highlights the importance of effective service recovery in building customer loyalty and turning a potentially negative experience into a positive one. B N Rao suits' commitment to resolving the issue and going the extra mile to deliver a satisfactory outcome ultimately strengthened the customer's trust and loyalty in the brand.

There are 286 different possible selections of three candies from 13 varieties.

To find out how many possible selections can be made, we can use the combination formula: nCk = n! / (k! (n-k)!), where n is the total number of candies available and k is the number of candies to be selected.

In this case, n = 13 (the number of candy varieties) and k = 3 (the number of candies to be selected). So the number of possible selections can be calculated as follows: 13C3 = 13! / (3! (13-3)!) = 286. Therefore, there are 286 different possible selections of three candies from the 13 varieties available in the candy store.

Answer:

\(\boxed {\boxed {\sf D. \ r= -0.9874}}\)

Step-by-step explanation:

The correlation coefficient is a number between -1 and 1. It tells us the strength of the linear association and the direction.

We want to find the r-value indicating a strong negative correlation. A negative number indicates a negative correlation. Therefore, choices A and C can be eliminated, because they are positive numbers.

Now we are left with B (-0.1859) and D (-0.9874). The closer the r-value is to -1/1, the stronger the correlation. -0.9874 is much closer to -1 than -0.1859, so choice D is the stronger correlation.

it is seen that if the number of people in the group is n = 23, the probability that at least two people will have the same birthday is at least 1/2.

Let P(A) be the probability that in a randomly selected group of n people, at least two people have the same birthday.

If we assume that the year has 365 days, then the number of ways to select n people with different birthdays is n x (n-1) x (n-2) x ... x (n-364).

the probability of selecting n people with different birthdays is P(A') = n(n - 1)(n - 2)...(n - 364)/365nThen, the probability that at least two people in a group of n have the same birthday is given by P(A) = 1 - P(A').

We need to find the smallest value of n such that P(A) ≥ 1/2.Let's solve for this.Let us find n such that P(A) ≥ 1/2.

By using the complement rule, 1-P(A') = P(A).Then:1 - n(n - 1)(n - 2)...(n - 364)/365n ≥ 1/2n(n - 1)(n - 2)...(n - 364)/365n ≤ 1/2(2)n(n - 1)(n - 2)...(n - 364) ≤ 365n/2Now, take the natural logarithm of both sides and simplify as follows:ln[n(n - 1)(n - 2)...(n - 364)] ≤ ln[365n/2]nln(n) - ln[(n - 1)!] - ln[(n - 2)!] - ... - ln[2!] - ln[1!] ≤ ln[365n/2]

Therefore, we need at least 23 people in the group for the probability of two or more people having the same birthday to be at least 1/2.

This is because n = 23 is the smallest number for which the inequality holds, and therefore, it is the smallest number of people required to ensure that the probability of two or more people having the same birthday is at least 1/2.
