Let the following sample of 8 observations be drawn from a normal population with unknown mean and standard deviation: 22, 18, 14, 25, 17, 28, 15, 21. use table 2.a. calculate the sample mean and the sample standard deviation. (round intermediate calculations to 4 decimal places, "sample mean" to 3 decimal places and "sample standard deviation" to 2 decimal places.) sample mean sample standard deviation b. construct the 80% confidence interval for the population mean. (round "t" value to 3 decimal places, and final answers to 2 decimal places.) confidence interval to c. construct the 90% confidence interval for the population mean. (round "t" value to 3 decimal places, and final answers to 2 decimal places.) confidence interval to d. what happens to the margin of error as the confidence level increases from 80% to 90%? as the confidence level increases, the interval becomes narrower. as the confidence level increases, the interval becomes wider.
