Question 1

A population mean is to be estimated from the sample described. Round your answer to one decimal place if necessary. Assume that all confidence intervals use a 95% confidence level.

Margin of error = 0.06, sample size = 50, sample mean =  0.65
What is the 95% confidence interval for the population mean?
◦ 0.6 < μ < 0.7
◦ 49.9 < μ < 50.1
◦ 0.65 < μ < 0.7
◦ 0.5 < μ < 0.8

Question 2

Find an estimate of the sample size needed to obtain the specified margin of error for the 95% confidence interval of a population mean.

Margin of error = 6.3, sample standard deviation = 18
◦ 6
◦ 206
◦ 16
◦ 33
