The following hypotheses are given. h0 : σ1² = σ2² h1 : σ1² ≠ σ2² 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.
1. state the decision rule for 0.02 significance level. (round your answer to 1 decimal place.) reject h0 if f >
2. compute the value of the test statistic. (round your answer to 2 decimal places.)
3. at the 0.02 significance level, is there a difference in the variation of the two populations?
. there is in the variations of the two populations
