Extracted text: 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 75 dates, the mean record high daily temperature in a certain city has a mean of 82.74 F Assume the population standard deviation is 13.95 F. The 90% confidence interval The 95% confidence interval Interpret the results. O A. You can be certain that the mean record high temperature was within the 90% confidesce interval for approximately 68 of the 75 days, and was within the 95% confidence interval for approximately 71 of the 75 days. O B. 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. 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 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.
