Car Crash Tests Data Set 19 “Car Crash Tests” in Appendix B lists results from car crash tests. The data set includes crash test loads (pounds) on the left femur and right femur. When those loads are partitioned into the three car size categories of small, midsize, and large, the two-way analysis of results from XLSTAT are as shown below. (The row factor of femur has the two values of left femur and right femur, and the column factor of size has the three values of small, midsize, and large.) Use a 0.05 significance level to apply the methods of two-way analysis of variance. What do you conclude?

a. Construct a two-way (with interaction) ANOVA table for these data.
b. At the 5% significance level, can you conclude there is interaction between Ranks (Low, Medium, High) and Branch of Service?
c. Are you able to conduct tests on the main effects? If yes, conduct these tests at the 5% significance level.
Suppose that a magnet high school includes grades 11 and 12, with half of the students in each grade. Half of the senior class and 10% of the junior class are taking calculus. Create a hypothetical table of 200 students for this situation. Use grade (junior, senior) as the row variable.
