Question: Consider the leaf spring experiment in Exercise 14.9. Rework this problem, assuming that factors A, B, and C are easy to control but factors D

Consider the leaf spring experiment in Exercise 14.9. Rework this problem, assuming that factors A, B, and C are easy to control but factors D and E are hard to control.

Using equations (14.6) and (14.7), the mean and variance are:
Mean Free Height = 7.63 + 0.12A €“ 0.081B

Using ï³Ë†2 ï€½MSE ï€½ 0.02 :
Variance of Free Height = (0.046)2 + (€“0.12 + 0.077B)2 + 0.02

or (+0.046), ' (-0.12 + 0.07792 + 2
