Homework Help: Stats

Posted by Yasmin on Monday, December 6, 2010 at 10:02am.

I just need help with starting how to calculate the problem I am so lost.

A random sample of eight observations from the first population resulted in a standard deviation of 10. A random sample of six observations from the second population resulted in a standard deviation of 7. At the .02 significance level, is there a difference in the variation of the two populations?
