Need help on understanding this 

  From thr chapter to this, I am not getting any answer that is close 

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 55 dates, the mean record high daily temperature in a certain city has a mean of 82.92°F Assume the population standard deviation is 13.52°F.
The 90% confidence interval is (. ).
(Round to two decimal places as needed.)
The 95% cofidence interval is
(Round to two decimal places as needed.)
(. D.
Which interval is wider? OChoose the correct answer below.
The 95% confidence interval
O The 90% confidence interval
Interpret the results.
O A. You can be certain that the mean record high temperature was within the 90% confidence interval for approximately 50 of the 55 days., and was within the 95% confidence interval for approximately 52 of the 55 days.
OB. 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.
C. 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.
O D. 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.
