[5) In an experiment to compare the tensile strengths of 5 different types of copper wire, a pooled t-test with or = .05 was used to group the types of wire according to equal pairwise mean strength. The major problem that will result from this procedure is A. the experimentwise Type I error rate will be much larger than the nominal o: = .05 of the t-test. the number of tests that need to be conducted is excessive. the assumption of independence will be violated. the Type II error rate will not be constant. F9579?\" none of the above, this is the proper procedure. [6) If a F-test is used to test the signicance of 8 contrasts constructed from 15 treatment means, at what value must orpc be set in order to achieve a familywise error rate of op =0 .01? A. 0.01 because the Ftest is insensitive to multiple testing. 0.01f8 because there were 8 tests conducted. 0.01;I 15 because there were 15 population means 0.01f120 to adjust for both the number of tests and population means.
