Chapter B.5, Problem 18AYU

SAT Test Scores A researcher wants to know if students who do not plan to apply for financial aid had more variability on the SAT I math test than those who plan to do so. She obtains a random sample of 35 students who do not plan to apply for financial aid and a random sample of 38 students who do plan to apply for financial aid and obtains the following results:

Do Not Plan to Apply for Financial Aid Plan to Apply for Financial Aid
n1 = 35 n2 = 38
s1 = 123.1 s2 = 119.4

Do students who do not plan to apply for financial aid have a higher standard deviation on the SAT I math exam than students who plan to apply for financial aid at the α = 0.01 level of significance? SAT I math exam scores are known to be normally distributed.
