Unformatted text preview: response for each level of the factor. 5. Carry out the hypothesis test where the null hypothesis is that all subpopulation mean blood coagulation times are equal versus the alternative that at least one is diﬀerent at the 5% signiﬁcance level. (a) What assumptions must be made. State H and H a . (b) Specify the test statistic realization and pvalue. (c) What is the distribution of the test statistic when H is true. State the values for its parameters. (d) State the conclusion to this test. Based on this conclusion, what type of error could you be making? (e) Report Tukey HSD simultaneous 95% conﬁdence intervals for the pairwise diﬀerences between the subpopulation means of blood coagulation times. Interpret this set of intervals and mention which pairs of subpopulation means are statistically signiﬁcantly diﬀerent at the simultaneous 5% signiﬁcance level. 1...
