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 confident a random sample of 72 dates, the mean record high daily temperature in a certain city has a mean of 86.17 F. Assume the population standard deviation is 14.16 F. % confidence interval is (). to two decimal places as needed.) %% confidence interval is (].)- to two decimal places as needed.) terval is wider? Choose the correct answer below. 80% confidence interval 95% confidence interval the results. u can be certain that the mean record high temperature was within the 90% confidence interval for approximately 65 of the 72 days, and was within the 95% confidence interval for approximately 68 of the 72 days. u 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. u 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. 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
