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 confidence intervals From a random sample of 78 dates, the mean record high daily temperature in a certain city has a mean of 86.28 F. Assume the population standard deviation is 14.89 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. The 90% confidence interval The 95% confidence interval Interpret the results A. You can be certain that the mean record high temperature was within the 90% confidence interval for approximately 70 of the 78 days, and was within the 95% confidence interval for approximately 74 of the 78 days. B. 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 O C. 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. O D. 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.
