a. Which main effects are significant for crack length? Are there significant interactions?
Above are the main effect factors as well as the interaction effects for y.
ME(A) = z (A+) z(A-)

32. The ANOVA analysis ignores potential effect of initial pressure, where the ANCOVA although
it cannot control the effect, it can measure it.
At a level of alpha = 0.05, there is not a significant difference between substance

Due: February 18, 2016
Will do multiple comparison with t-statistics from first table using Tukey method, but we will use
new table mean squared error.

Design of Experiments
1. (3)Give examples of hard-to-change factors. How do you reconcile the hard-to-change nature of the
factor with the need for randomization?
Hard-to-change factors are those that are not easily adjusted due to time o

1. (Chapter 2, #10) What do you learn from the plot (given in book)? How do you modify your
model and analysis?
The plot shows residuals, r_i, vs x_i, the different machines. We look for a p
