Explanation / Answer

1)

Frequency = 7 percentage = 14%

2)

Percentage of reTred = number of reTred/ sample size × 100

Sample mean = [42+49]/2 = 46

= [sample size – 14]/46 × 100 = [ 42-14]/46× 100 = 61%

Percentage on sick leave = sample size on leave/ sample size × 100 = 14/91 × 100 = 15%

3)

total sample size of the study = 42+41 = 91

Frequency of the sample = 7+7 =14

Percentage of the total sample which were still employed

= [total percentage – reTred] = [100-61] = 39%
