The file P02_07.xlsx includes data on 204 employees at the (fictional) company Beta Technologies. For this problem, consider this data set as the population frame.
a. Using the method in this section (not StatTools), generate a simple random sample of size 20 from this population.
b. Use StatTools to generate 10 simple random samples of size 20 from this population.
c. Calculate the population mean, median, and standard deviation of Annual Salary. Then calculate the sample mean, median, and standard deviation of Annual Salary for each of the samples in parts a and b. Comment briefly on how they compare to each other and the population measures.
