The city manager of Grand Rapids, Michigan, has instructed her assistant to compile data on employee travel reimbursement payments for the past year. Th ere were a total of 250 reimbursement claims. As part of her cost management initiatives, the manager would like to get a better sense of what these reimbursement data look like—that is, to understand the important characteristics of the distribution, including range, average, and dispersion. Assist the manager by calculating the mean, median, mode, and standard deviation for these data (reimbursements per trip in dollars).

Next, use a statistical package program such as SPSS, STATA, or the like to create a frequency distribution for the reimbursement data. Use your discretion when determining the number of categories in the distribution. To get started, make sure first to calculate the range for these data.
