Answer:
20%
Explanation:
The question has a Mean of 1 day and the Standard deviation is 4 days, So it is apparent that in every Five days including the 4 days standard deviation, we have the chipper to be available and clients in need of it can rent it for 1 day.
Therefore if the chipper is going to be rented on the 1st day, it would be rented again after 4 days, on the 5th day.
utilization for the chipper will be
= (1/5) x 100
= 0.2 x 100
= 20%
