Answer 1

The mileage that the supervisor will achieve that is within a z-score of 1.5 is; 23.6

How to find the z-score?

Formula for z-score in statistics is;

z = (x' - μ)/s

Where;

x' is sample mean

μ is population mean

s is sample standard deviation

We are given;

x' = 29

Standard deviation; s = 3.6

z = 1.5

Thus;

1.5 = (29 - μ)/3.6

μ = 29 - (1.5 × 3.6)

μ = 23.6
