Asupervisor finds the mean number of miles that the employees in a department live from work. which mileage is within a z-score of 1.5? a. 21 miles b. 24 miles c. 36 miles d. 41 miles

The z-score tells you how many standard deviations from the mean. 

1.5 * 3.6 = 5.4 miles 

So anything within 5.4 miles of the average (29). 

The range would be: 
29 - 5.4 = 23.6 
to: 
29 + 5.4 = 34.4 

23.6 ≤ x ≤ 34.4 

 
B) 24 miles
