Please help and if possible explain why we had to use either stdev or stdevp for net income, comprehensive income, and operating cash flow. Thank you!

Consider the Throwback Company's financial results for Years 1 - 5 (see excel). ExcelData For each year, calculate the percentage change in: Net Income Comprehensive Income (Remember: Comp Inc = Net Income + Other Comp Income) Operating Cash Flow Using the percentage change for the Years 3, 4 and 5, calculate the standard deviation (assuming the population) for: Net Income Comprehensive Income Operating Cash Flow (Hint: make sure you know the difference between Estdev() and =stdevp() in excel.) Round your answers to the nearest percentage point(e.g. 29.64983% should be entered as 30, not.30). Throwback Inc.
