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 random sample of 79 dates, the mean record high daily temperature in a certain city has a mean of 85.23 F. Assume the population standard deviation is 13.98"F. confidence interval is ()- to two decimal places as needed.) confidence interval is ()- two decimal places as needed.) erval is wider? Choose the correct answer below. 90% confidence interval 95% confidence interval e results. 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 inter 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. 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. can be certain that the mean record high temperature was within the 90% confidence interval for approximately 71 of the 79 days, and was within the 95% confidence interval for approximately 75 of th
