Consider the analysis of a 22 designed experiment with 5 replicates. Use the following partially complete Minitab output to answer the following questions.
(a) Find all of the missing values in the analysis of variance table.
(b) Use this table to test for significance of the effects. Use α =0.05.
(c) Compute the estimated standard error of each effect.
(d) Find all of the missing values in the t-tests of the following effects table. Indicate which effects are significant. Use α =0.05.
(e) Write the least squares fitted model using only the significant terms.
(f) Use the model to predict the response when and x2 = 1.
