Mm4 At a certain restaurant in Ohio, the number of minutes that diners spend at the table has a major impact on the profitability of the restaurant. Suppose the average numberof minutes that diners spend at a table for dinner at the restaurant is 93 minutes with a standard deviation of 19 minutes. Assume the number of minutes diners spend attheir table follows the normal probability distribution. Complete parts a through d.a. Calculate the probability that the average number of minutes that diners spend at their table for dinner will be less than 100 minutes using a sample size of 9 tables.(Round to three decimal places as needed.)b. Calculate the probability that the average number of minutes that diners spend at their table for dinner will be less than 100 minutes using a sample size of 21 tables.(Round to three decimal places as needed.)c. Calculate the probability that the average number of minutes that diners spend at their table for dinner will be less than 100 minutes using a sample size of 30 tables.(Round to three decimal places as needed.)d. Explain the difference in these probabilities. Choose the correct answer below.O A. With a larger sample size, the standard error of the mean increases and the sample means tend to move closer to the population mean of 93 seconds. Therefore,the probability of observing a sample mean less than 100 seconds increases as the sample size increases.O B. With a larger sample size, the standard error of the mean increases and the sample means tend to move further away from the population mean of 93 seconds.Therefore, the probability of observing a sample mean less than 100 seconds decreases as the sample size increases.Oc. With a larger sample size, the standard error of the mean stays the same and the sample means stay the same. Therefore, the probability of observing a samplemean less than 100 seconds decreases as the sample size increases.O D. With a larger sample size, the standard error of the mean decreases and the sample means tend to move closer to the population mean of 93 seconds. Therefore,the probability of observing a sample mean less than 100 seconds increases as the sample size increases.
