1. Find the critical value tc(little) for a confidence level, c= 0.99 and a sample size, n = 16

2.Find the maximum error, E, for the population mean, given c = 0.95, standard deviation, s = 5 and sample size, n = 16

3.Find the maximum error, E, for the population mean,given c = 0.99, standard deviation, s = 3 and sample size, n = 6

4.Use the TI-84 or otherwise determine the confidence interval for the population meanfor a t-distribution given c = 0.90, x-bar = 12.5, s = 2.0 and n = 6()
