Special Problem 2A Exploring Normal Distributions The purpose of this special problem is to investigate the behavior of the means and standard deviations of repeated samples of size 25 taken from normal distributions. The statistics software package, Excel, has the ability to generate values of variables from various distributions, including normal distributions with specified mean and standard deviation. For this investigation, you will obtain 25 observations from ( 29 15 , 100 N distribution, and calculate certain descriptive measures for these observations. You will repeat this procedure a number of times and then study the results. Procedure. 1. Generate 25 values from the ( 29 15 , 100 N distribution and put the values in column 1. The values should be near 100 and will have decimal parts to the numbers. Hint: Generate the numbers in Excel and then place them into Excel, or charts from internet. 2. Now calculate one-variable statistics on this data.
