Preschool Attendance and High School Graduation Rates for Males The Perry Preschool Project data presented in exercise $10.39$ can be divided to see whether there are different effects for males and females. The table shows a summary of the data for males (Schweinhart et al. 2005).

a. Find the graduation rate for males who went to preschool, and compare it with the graduation rate for males who did not go to preschool.

b. Test the hypothesis that preschool and graduation are associated, using a significance level of $0.05$.

c. Exercise $10.40$ showed an association between preschool and graduation for just the females in this study. Write a sentence or two giving your advice to parents with preschool-eligible children about whether attending preschool is good for their children’s future academic success, based on this data set.
