Construct the indicated confidence interval for the population mean using the t-distribution. Assume the population is normally distributed.

cequals

c = 0.99, x overbar = 13.1, s = 2.0, n = 8

c = 90, x overbar = 13.7, s = 0.65 n = 17

Use the confidence interval to find the margin of error and the sample mean.

left parenthesis 0.224 comma 0.360 right parenthesis
