QUESTION
A consumer advocate magazine conducts an experiment.
A consumer advocate magazine conducts an experiment. A random sample of fifteen service times are recorded (purchases are made at randomly chosen Gargantuan Burger restaurants, at randomly chosen times). Then a one-sided t-test is performed at a 5% significance level to determine whether the average service time appears significantly longer than 90 seconds. What is the actual average service time? What critical value should be used in the magazine"s hypothesis test?
