A bank branch located in a commercial district of a city has developed an improved process for serving customers during the noon-1:00pm lunch period. The waiting time of all customers during this hour is recorded over the period of a week. A random sample of 30 customers is selected and their waiting time is recorded (see data file Bank 1). At the 0.05 level of significance is there evidence that the population mean waiting time is less than 5 minutes?
