Question
In order to plan properly for production, a firm must have adequate inventory. One factor influencing the inventory policy of a firm is the standard deviation of lead time, which is the time between when goods are ordered and when they actually arrive.
A computer manufacturing firm is investigating the possibility of having parts shipped using ShipCo lines. The computer firm has obtained shipping information for a sample of 36 orders made to ShipCo by comparable computer firms. The lead times are summarized in the histogram below.
Based on this histogram, estimate the standard deviation of the sample of 36 lead times.
Carry your intermediate computations to at least four decimal places, and round your answer to at least one decimal place.
