A manager in a supermarket wants to estimate the waiting time at the checkout. She would like to measure the average change in wait time as the number of customers increases in the store. Data on the total number of customers in the store and the waiting times (in minutes) were recorded. The fitted linear regression equation is given below. Å· = -0.83 + 0.16x Predict the waiting time if there are 25 customers in the store. It is ________ minutes.

Waiting Time At a certain grocery checkout counter, the average waiting time is 2.5 minutes. Suppose the waiting times follow an exponential density function. a. Write the equation for the exponential distribution of waiting times. Graph the equation and locate the mean waiting time on the graph. b. What is the likelihood that a customer waits less than 2 minutes to check out? c. What is the probability of waiting between 2 and 4 minutes? d. What is the probability of waiting more than 5 minutes to check out?

The manager of a grocery store has taken a random sample of 100 customers. The average length of time it took the customers in the sample to check out was 3.1 minutes. The population standard deviation is known to be 0.5 minutes. We want to test to determine whether or not the mean waiting time of all customers is significantly more than 3 minutes. At a 0.05 level of significance, it can be concluded that the mean of the population is _____.
