sample size = 49, sample mean = 25.2 cm, sample standard deviation = 2.2 cm Assume that population means are to be estimated from the samples described. In each case, use the sample results to approximate the margin of error and 95% confidence interval.

95% confidence interval E=margin of error E = margin of error -E

95% confidence interval E=margin of error E = margin of error -E Sample proportion p P+E
