A major fast food restaurant chain claims the mean waiting time for customers is 3.0 minutes. A random sample of 25 customers was elected and the waiting time recorded. The mean waiting time was found to be 3.30 minutes with a standard deviation of 1.00 minute. Using the p-value approach, perform the appropriate test of hypothesis. Use α = 0.05. Let µ = true average waiting time. Use the information to complete Questions 1 - 8. 1. What is the appropriate null hypothesis?
