The following hypotheses are given:
Ho: s2 sub 1 = s2 sub 2
H1: s2 sub 1 = s2 sub 2
A random sampleof five observations from the first population resulted in a standard deviationof 12. A random sample of seven observations from the second population showed a standard deviation of 7. At the .01 significance level, is there more variation in the first population?
(1) Calculate your test statistic. The F statistic is calculated by dividing one of the standard deviations by the other. Choose which goes in the numerator and which goes in the denominator so that F is greater …
