You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. From a random sample of 63 dates, the mean record high daily temperature in a certain city has a mean of 84.50°F. Assume the population standard deviation is 14.11°F. The 90% confidence interval is (nothing,nothing). (Round to two decimal places as needed.) The 95% confidence interval is (nothing,nothing). (Round to two decimal places as needed.) Which interval is wider? Choose the correct answer below. The 95% confidence interval The 90% confidence interval Interpret the results. A. You can be 90% confident that the population mean record high temperature is between the bounds of the 90% confidence interval, and 95% confident for the 95% interval. B. You can be certain that the population mean record high temperature is either between the lower bounds of the 90% and 95% confidence intervals or the upper bounds of the90% and 95% confidence intervals. C. You can be certain that the mean record high temperature was within the 90% confidence interval for approximately 57 of the 63 days, and was within the 95% confidence interval for approximately 60 of the 63 days. D. You can be 90% confident that the population mean record high temperature is outside the bounds of the 90% confidence interval, and 95% confident for the 95% interval.

From a random sample of

dates, the mean record high daily temperature in a certain city has a mean of

84.50°F.

Assume the population standard deviation is

14.11°F.

The 90% confidence interval is

(nothing,nothing).

(Round to two decimal places as needed.)

The 95% confidence interval is

(nothing,nothing).

(Round to two decimal places as needed.)

Which interval is wider? Choose the correct answer below.

The 95% confidence interval

The 90% confidence interval

Interpret the results.

You can be 90% confident that the population mean record high temperature is between the bounds of the 90% confidence interval, and 95% confident for the 95% interval.

You can be certain that the population mean record high temperature is either between the lower bounds of the 90% and 95% confidence intervals or the upper bounds of the90% and 95% confidence intervals.

You can be certain that the mean record high temperature was within the 90% confidence interval for approximately

of the

days, and was within the 95% confidence interval for approximately

of the

days.

You can be 90% confident that the population mean record high temperature is outside the bounds of the 90% confidence interval, and 95% confident for the 95% interval.
