Here's a F-table that should help.

Also, remember that
I get (1/0.481414)=2.0772.... using 19,29,.95 in that calculator.
Grades for 2 classes, X and Y
X:78,89,81,94,60,67,51,73,90,93,81,68,45,100,60,10 2,95,87,85,96,77,79,55,89,86,75,85,76,95,84
I calculated , and n=30
Y:65,95,94,72,56,87,89,28,71,78,54,93,91,68,88,90, 69,78,69,91
, and m=30
a. test the hypothesis against the alternative at the significance level assuming X and Y are and where
I started by using and critical region
b. test the hypothesis against the alternative hypothesis at the =10% significance level.
I started this part with and I don't know how to do this because 29 and 19 are not in the table. If this equality is true though then is H0 rejected?
