6.1.23 construct the confidence interval for the population mean μ
6.1.23 construct the confidence interval for the population mean μ
c = 0.98, x̅ = 15.7, σ = 4.0, and n=65
A 98% confidence interval for μ is OD (Round to one decimal place as needed.)
6.1.27 Use the confidence interval to find the margin of error and the sample mean (1.58,2.06)
The margin of error is (Round to two decimal places as needed.)
