In a Q system, the demand rate for strawberry ice cream is normally distributed, with an average of 290 pints per week. The lead time is 7 weeks. The standard deviation of weekly demand is 16 pints.

What is the standard deviation of demand during the 9 week lead time?

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

c. (3,2,6) is the answer.

a: 1/6, j: 1/4

step-by-step explanation: you are welcome
