1. Construct the confidence level for the population mean,.c = .90,sample mean = 0.0925sample deviation = 0.0013n = 45

2.Given a confidence level c = 0.80, a sample size, n = 22, a sample standard deviation, s = 3.2 and a sample mean, x-bar = 3.7, find each of the following.

a. the critical value tc

b. The maximum error, E, for the data.

c. the confidence interval
