The analysis of variance table for a \(3 \times 4\) factorial experiment, with factor A at three levels and factor B at four levels, and with two observations per treatment is shown here:
Source, df, SS, MS, F
A, 2, 5.3
B, 3, 9.1
AB, 6,
Error, 12, 24.5
Total, 23, 43.7
a. Fill in the missing items in the table.
b. Do the data provide sufficient evidence to indicate that factors A and B interact? Test using \(\alpha \alpha=.05\). What are the practical implications of your answer?
c. Do the data provide sufficient evidence to indicate that factors A and B affect the response variable x? Explain.

A balanced experimental design has a sample size of \(n=11\) observations at each of \(k=3\) factor levels. The sample averages are \(\overline{x}_{1⋅}=48.05,\overline{x}_{2⋅}=44.74, and\ \overline{x}_{3⋅}=49.11, and\ MSE=4.96\).
(a) Calculate pairwise confidence intervals for the factor level means with an overall confidence level of 95%.
(b) Make a diagram showing which factor level means are known to be different and which ones are indistinguishable.
(c) What additional sampling would you recommend to reduce the lengths of the pairwise confidence intervals to no more than 2.0 ?

What are the treatments for a designed study that utilizes one qualitative factor with four levels: A, B, C, and D?

The two-way table summarizes data from an experiment comparing the effectiveness of three different diets (A, B, and C) on weight loss. Researchers randomly assigned 300 volunteer subjects to the three diets. The response variable was whether each subject lost weight over a 1-year period. \(\text{Diet}\ \text{Lost weight?}\)

\(\begin{array}{l|c|c|c|c} & \mathrm{A} & \mathrm{B} & \mathrm{C} & \text { Total } \\ \hline \text { Yes } & & 60 & & 180 \\ \hline \text { No } & & 40 & & 120 \\ \hline \text { Total } & 90 & 100 & 110 & 300 \end{array}\)

Suppose we randomly select one of the subjects from the experiment. Show that the events "Diet B" and "Lost weight" are independent.
