The results of a paired-difference test are shown below to the right. d= - 4.2 a. Construct and interpret a 99% confidence interval estimate for the paired difference in mean values. So = 0.25 b. Construct and interpret a 90% confidence interval estimate for the paired difference in mean values. n = 16 a. 0 (Round to two decimal places as needed.) Choose the correct answer below. O A. Approximately 99% of the differences will be contained in the interval. O B. There is a 99% chance that the true population mean is contained in the interval. O C. If many random samples of this size were taken and intervals constructed, 99% of them would contain the true population mean. O D. This interval will contain the true population mean 99% of the time. b. ( (Round to two decimal places as needed.) Choose the correct answer below. O A. There is a 90% chance that the true population mean is contained in the interval. O B. If many random samples of this size were taken and intervals constructed, 90% of them would contain the true population mean. O C. Approximately 90% of the differences will be contained in the interval. O D. This interval will contain the true population mean 90% of the time
