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 confiden intervals From a random sample of 65 dates, the mean record high daily temperature in a certain city has a mean of 86.77°F Assume the population standard deviation is 13.56 F The 90% confidence interval is (Round to two decimal places as needed.) The 95% confidence interval is (Round to two decimal places as needed) Which interval is wider? Choose the correct answer below O The 90% confidence interval O The 95% confidence interval Interpret the results OA 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 OB. 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 90% confidence interva OG 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% OD. You can be certain that the mean record high temperature was within the 90% confidence interval for approximately 50 of the 65 days, and was within the 95% confidence interval for approximately 52 of the 65 days
