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 in andom sample of 79 dates, the mean record high daily temperature in a certain city has a mean of 85.190F. Assume the population standard deviation is 14.53"F. confidence interval is (],). to two decimal places as needed.) confidence interval is (] to two decimal places as needed.) nterval is wider? Choose the correct answer below. e 95% confidence interval e 90% confidence interval t the results. 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. You 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 the 79 days. 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. 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
