There is probably some variation in the exact measurements you obtained for each of the settings you used for the variables number-of-books and launcher-position. However, this variation should be relatively small. Therefore, you can assume that each of the four settings has a single value. Based on this assumption, you can view each setting as a different treatment.
1. Based on your analysis of each explanatory variable, which (if any) of these variables has a significant impact on the distance the penny traveled? State your conclusion with regard to both 1% and 5% significance levels (a).
2. Do your data violate any of the requirements of the ANOVA analysis?
