Unformatted text preview: α = 0 . 05 . (a) State the hypotheses of the oneway ANOVA F test. (b) Calculate the value of the test statistic. (c) In the next steps, we will compare this test statistic value to an F distribution. What values of df 1 and df 2 should that F distribution have? (d) Using an F table, identify the value of the test statistic that would correspond to a pvalue of 0.05. (e) For our data, is the pvalue larger or smaller than 0.05? (f) Make a decision about H , and interpret this decision in terms of what it says about the brands of golf balls. (g) Suppose we reject H in part (f), how many diﬀerent pairwise comparisons would there be ? (h) The Margin of Error (ME) calculated on the basis of Tukey’s 95% simultaneous conﬁdence level is 5.54, using this ﬁnd which pairs of the true brand mean distances do not diﬀer signiﬁcantly?
