The final steps in the process are to interpret the results, post your spreadsheet and data interpretation, and then discuss the information with your colleagues. Answer the following questions:What is the mean of your sample? What is the standard deviation of your sample?What is the z score, and is it unusual? Why or why not?What is the "shape" of the distribution? Is it skewed to the right or left?Do we have enough evidence to support the idea that the ACME Altimeter has an unusually large error issue?If the "acceptable error rate" is 75 feet, do the differences in the data really matter?
