A random sampleof eight observations from the first population resulted in a standard deviationof 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?
Ho: variances are equal
H1: variances are not equal
Please see the attached file for the solution.
at the .02 significance level, is there a difference in populations?
ho: variances are equal
This solution shows the steps and answer for a basic statistics hypothesis testing problem.
