A guidance counselor claims that high school students in acollege preparation program have higher ACT scores than those in ageneral program. The sample mean ACT score for 49 high schoolstudents who are in a college preparation program is 22.2 and thesample standard deviation is 4.8. The sample mean ACT score for 44high school students who are in a general program is 20.0 and thesample standard deviation is 5.4.
Use an 8% level of significance to conduct test the guidancecounselor’s claim. Assume the distribution of ACT scores for bothprograms are approximately normally distributed. Assume that?college prep2 ‡?general2 .
H0: Level of significance (?): ?=
HA: Type test: two-tailed left tail right tail
