Higher standard deviation on the math sat


A researcher wanted to know if students who do not plan to apply for financial aid had more variability in SAT math test than those who plan to do so. The summarized results are as follows:

Do not plan to apply for finanial aid Plan to apply for financial aid

n= 35 38

s= 123.1 119.4

Do students who do not plan to apply for financial aid have a higher standard deviation on the math SAT than students who plan to apply for financial aid at the alpha = 0.01 level of significance? (Assume normality)

Calcualte F* = (Round to 2 decimal places)?

p-value (symbol) (value)?

Decision (Enter R for reject Ho and F for fail to reject Ho)?
