An agriculturist claims that she has cultivated a new variety of orange that has a significantly higher content of vitamin C than the variety that is currently the top seller. A random sample of 15 oranges of the new variety and a random sample of 13 oranges of the current top seller were sampled, giving the following results: n1 = 15 s? = 6.4460 n2 = 13 s3 = 9.0336 %3D 3.1 Test for the equality versus inequality of population variances using a significance level of 10%. Remember to include a picture of the rejection region showing both critical values (for the purpose of finding both critical values you will have to make use of Excel). 3.2 Which hypothesis test would be appropriate to determine whether the new variety of orange has a significantly higher content of vitamin C than the variety that is currently the top seller? Do NOT perform a hypothesis test – simply tell me which test should be used, why you chose this test, and give the formula for the test statistic.
