Capital Expenditure Time Interval 1.5 FY1601 3.1 FY1604 2.5 FY1702 2.1 FY1703 3.3 FY18Q2 4.1 FY1804 (a) Write down and compute a Riemann sum that gives the approximate total capital expenditures for fiscal years 2016-2018, Because of the missing data, your Al's may have different lengths. (b) Will everyone have the same answers for part (a)? Why or why not? (c) Good news! Some of the missing data has been found. Our chart now reads: Capital Expenditure Time Interval 1.5 FY16Q1 2.0 FY1602 3.1 FY1604 2.5 FY17Q2 2.1 FY17Q3 3.3 FY17Q4 2.7 FY18Q1 3.3 FY1802 4.1 FY1804 Use a Riemann sum to approximate total capital expenditures for the three-year period. Do you think this is a better approximation than what you computed in part (a)? Why or why not?7.21. The following is actual data from Microsoft regarding capital expenditures (in billions of dollars per quarter) over a three-year period. The notation FY1601 means "Fiscal Year 2016 Quarter 1". Unfortunately, we only have data for six of the twelve quarters
