Clara · Answer 1

mean m = 94

standard deviation = 10

This problem relates to normal distribution.

For 95.4 % possibility the deviation must not exceed 2 x standard deviation

or no of jobs should fall within range of

94 + or - 2 x 10

94 + 20 = 104

94 - 2 x 10 = 74

no of job should fall between

104 and 74
