Number of active military personnel (in 1 ,OOOs) from different regions Region Pacific West North Central South Atlantic Mountain East North Central Middle Atlantic West South Central East South Central New England Source: U.S. Census Bureau, 2012; Active military personnel 299 64 376 89 26 41 177 68 8 Note: the variable is the number of active military personnel and the sampling unit are regions. First: 1. Calculate the population mean (avg. number of personnel in the 9 regions) and standard deviation. To make this easier, you can use an online calculator to do the calculations for you. Here is a convenient website: https://www.calculator.net/standard-deviation-calculator.html Next, draw a random sample from the population with a sample size of n = 4 regions. You can pick any 4 regions to form the sample (e.g., Pacific, Mountain, South Atlantic, New England). Then, calculate the mean of the sample. Do this sampling procedure 5 times, each time drawing a different random sample of 4 regions. For each sample that you select, calculate the mean of the sample. 2. List the sample mean for each of your 5 samples: Mean of Sample 1: Mean of Sample 2: Mean of Sample 3: Mean of Sample 4: 3. 4. What is the mean of the 5 sample means? How does this compare to the population mean? Mean of Sample 5: 73 OF 9:02 PM 5/15/2022
