This problem will take you through calculating the mean for grouped data by hand. Part A: Lower Class Limit Upper Class Limit Frequency 50 55 065 70 75 80 85 90 54 59 64 69 74 79 84 89 1 1 4 7 8 12 15 18 10 Class midpoint 67.5 72.5 77.5 82.5 87.5 92.5 Frequency times midpoint Part C: Now add up the third column of your table. (The frequency column.) 472.5 580 930 1237.5 1575 925 94 Part B: Now add up the last column of the table above. (The frequency times midpoint column.) Part D: Now divide your answer to Part B by your answer to Part C. This is the mean for the Grouped Frequency Data Table (GFDT). Round your answer to one decimal place.
