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 59 dates, the mean record high daily temperature in a certain city has a mean of 84.52°F. Assume the population standard deviation is 14.57°F. The 90% confidence interval is (OD). (Round to two decimal places as needed.) The 95% confidence interval is (OD). (Round to two decimal places as needed.) Which interval is wider? Choose the correct answer below. O The 90% confidence interval O The 95% confidence interval

Question
Interpret the results.
O 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.
O 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 the 90% and 95% confidence intervals.
OC. You can be certain that the mean record high temperature was within the 90% confidence interval for approximately 53
of the 59 days, and was within the 95% confidence interval for approximately 56 of the 59 days.
O 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.
