You have taken a random sample of sizen & 95of a normal population that has a population mean ofu = 140and a population standard deviation ofo 23. You sample, which is Sample 1 in the following table, has a mean of x = 141.3. (In the table, Sample 1 is indicated by "M1", Sample 2 by "M2", and so on.) (to) Based on Sample 1, plot the confidence intervals of80%and95%for the population mean. Use1,282as the critical value for the confidence interval o 80%and use1960 as the critical value for the confidence interval of 95%. (If necessary, you can refer to a list of formulas.) • Write the upper limit and the lower limit on the graphs to indicate each confidence interval. Write the answers with one decimal place. . For the points (and), write the population mean,μ = 140. 128.0 128.0 80% confidence interval 139.0 150.0 150.0 128.0 128.0 95% confidence interval 139.0 150.0 150.0

![You have taken a random sample of sizen & 95of a normal population that has a population mean ofμ = 140and a population standard deviation ofo = 23. Your
sample, which is Sample 1 in the following table, has a mean ofx = 141.3. (In the table, Sample 1 is indicated by "M1", Sample 2 by "M2", and so on.)
(to) Based on Sample 1, plot the confidence intervals of80%and95%for the population mean. Use1,282as the critical value for the confidence interval of
80%and use1960 as the critical value for the confidence interval of95%. (If necessary, you can refer to a list of formulas .)
• Write the upper limit and the lower limit on the graphs to indicate each confidence interval. Write the answers with one decimal place.
• For the points (♦and ◆), write the population mean, μ = 140.
