Question 71

The Bar graph given below presents the number of female employees working in two factories on six different days of a week.

What is the difference (correct up to two decimal places) in the average number of females working per day in a factory F1 and the average number of females working per day in a factory F2?

Solution

the average number of females working per day in a factory F1

avg1 = $$\frac{280+262+314+328+336 +444}{6}$$ = 327.33

the average number of females working per day in a factory F2

avg1 = $$\frac{186+212+224+232+285 +272}{6}$$ = 235.16

difference in avg = 327.33 -235.16 = 92.17
