A quick method to calculate the mean (equal share value) is to add up all the values and then divide by the number of values.
Total height = 139 + 145 + 150 + 136 + 152 + 144 + 138 = 1004
Number of values = 7
Mean = Total height / Number of values = 1004 / 7 = 143.43
Therefore, the equal share value (mean) of the heights is 143.43.
The correct answer is B. 143.43.
Use the frequency table to calculate the equal share value (mean) of the heights.
139+145+150+136+152+144+138
A 143.7
B 143.43
C 179.63
D 100.4
