In Meijer supermarket, the customer's waiting time to check out is approximately normally distributed with a standard deviation of 2.5 minutes. A sample of 25 customer waiting times produced a mean of 8.2 minutes. Is this evidence sufficient to reject the supermarket's claim that its customer checkout time averages no more than 7 minutes? Complete this hypothesis test using the 0.02 level of significance. a. Solve using the p-value approach. b. Solve using the classical approach
