Question:
14.75 The suggested queuing time in a fast-food restaurant is 10 minutes. Of a random sample of 50 customers, 8 expected to be in queue for more than 10 minutes, 27 expected to be in queue for less than 10 minutes, and the remaining expected to be in queue for exactly 10 minutes. Do these data present strong evidence that, for the population of customers’ queuing time, more customers expect to be in queue for less than 10 minutes compared with those expecting to be in queue for more than 10 minutes?
