A small computing center has found that the number of jobs submitted per day to its computers has a mean of 94 jobs and a standard deviation of 10. Where do we expect the number of jobs per day to fall most of the time (95.4%) ?

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
