A sample of 135 items resulted in sample mean of 14.09 and a sample standard deviations of 9.11. Construct a 95.21% confidence interval estimate for the population mean. Enter the upper bound of the confidence interval. (Round to the nearest thousandth.)
STATDISK has the ability to construct a confidence interval estimate for the mean. The next questions are designed to introduce you to these functions within STATDISK. For more information, please review the following tutorial. Always feel free to pause and/or restart the video.
