a. Calculate the average and standard deviation of waiting time at banks and hospitals. b. Assuming the population variance is the same, determine the estimated limits of the difference between the average waiting time from the survey results from the survey with a significance level of 5%? c. Do the same thing for significance level of 10%, what is your conclusion about the differences with 5% significance level?
