Question

There are four estimates made for the anticipated cycle time to produce a subcomponent. The estimates, in seconds, are 10, 20, 30, and 64. If the first two estimates have equal weights, which total 70%, and the last two are weighted equally with the remaining 30%, what is the expected time?

The expected time is  seconds.

Answer 1

The expected time = (10 * 0.35) + (20 * 0.35) + (30 * 0.15) + (64 * 0.15)

                              = 3.5 + 7 + 4.5 + 9.6

                              = 24.6

Thus, the expected time is 24.6 seconds.
