(2 pts)Explanation / Answer
Above is the frequency table.
Total number of people surveyed =147
Mean = 1 * 10 + 44 * 20 + 51 * 30 + 17 * 40 + 19 * 50 + 10 * 60 + 5 * 70 = 5000/147 = 34.013
Total people = 147
Median value = 147 + 1 / 2 = 74th value
74th value is in the group 25-35.
Estimated Median = 25 +( (147/2) -45 )/55 * 10 = 30.1818
Mode = The modal group is 25 - 35
= 25 + (51 - 44) / (51-44+51-17) * 10 = 26.707 = 26.71
Range = 51 - 1 = 50
