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 65 dates, the mean record high daily temperature in a certain city has a mean of 85.05.F. Assume the population standard deviation is 14. 14 F. The 90% confidence interval is ( 82.12 , 87.98 ) (Round to two decimal places as needed.) The 95% confidence interval is ( 81.55 , 88.55 ). Round to two decimal places as needed.) Which interval is wider? Choose the correct answer below. The 90% confidence interval The 95% 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.
