2. The average waiting time to be seated for dinner at a popular restaurant is 23.5 minutes, with a standard deviation of 3.6 minutes. Assume the waiting time follows a Normal distribution. When a customer arrives at the restaurant for dinner, find the probability that the customer will have to wait the following time. a) Less than 18 minutes b) More than 26 minutes c) Between 15 and 22 minutes d) Suppose there is a 10% chance that the customer will wait less than K minutes before he or she can seat for dinner. Find K. e) Suppose there is a 5% chance that the customer will wait more than K minutes before he or she can seat for dinner. Find K.

Step 1
We are given that the average waiting time (mean, μ) is 23.5 minutes, and the standard deviation (σ) is 3.6 minutes. The waiting time follows a Normal distribution. We need to find probabilities for different scenarios regarding the waiting time. Show more…

10.The average waiting time to be seated for dinner at a popular restaurant is 23.5 minutes, with a standard deviation of 3.6 minutes. Assume the variable is normally distributed. When a patron arrives at the restaurant for dinner, find the probability that the patron will have to wait the following time: a. Between 15 minutes and 30 minutes. b. Less than 10 minutes. c. More than 20 minutes.

The average waiting time to be seated for dinner at a popular restaurant is 23.5 minutes, with a standard deviation of 3.6 minutes. Assume the variable is normally distributed. When a patron arrives at the restaurant for dinner, find the probability that the patron will have to wait the following time. Find the range of usual values of waiting time.

1. A restaurant serves an average of 180 customers per hour during the lunch time. (a). What probability distribution is most appropriate for calculating the probability of a given number of customers arriving within one hour during lunch time? (b). What are the mean and the standard deviation of the number of customers this restaurant serves in one hour during lunch time? (c). Would it be considered unusually low if only 150 customers showed up to this restaurant in one hour during lunch time? (d). Calculate the probability that this restaurant serves 170 customers in one hour during lunch time?
