5 7 Refer to Exercise 5 5 Because the company is sampling the coffee production process every our there are 720 confidence intervals for the mean caffeine content u constructed every month a If the level of confidence remains at 95 for the 720 confidence intervals in a given month how many of the confidence intervals would you expect to fail to contain the value of u and hence provide an incorrect estimation of the mean caf feine content b If the number of samples is increased from 50 to 100 each hour how many of the 95 confidence intervals would you expect to fail to contain the value of u in a given month c If the number of samples remains at 50 each hour but the level of confidence is increased from 95 to 99 for each of the intervals how many of the 99 confidence intervals would you expect to fail to contain the value of in a given month
