Answer: 2 times the square root of 10
Explanation:
The following can be gotten from the question:
Lead time,l = 10 days
Daily demand,d = 10 gallons per day
Standard deviation,sd = 2 gallons
The standard deviation of demand during lead time will be calculated as:
= Standard deviation × ✓lead time
= 2 × ✓10
= 2✓10
= 2 times the square root of 10
