- Say you get a z-score of z = 0.35. Find 2 * Pr(Z ≥ |z|)Varric has conducted a within subjects ANOVA to determine if his band of pirates have significantly improved in their swashbuckling abilities over the past four months. The results of his analysis are as follows [F(3, 58) = 5.22, p = 0.07]. Should he run a post-hoc test? A. Yes, always run a post hoc test after conducting an ANOVA regardless of the result B. No, post hoc tests should only be conducted when an ANOVA yields a significant result C. No, post-hoc tests are not appropriate for a within subjects ANOVA D. Yes, post hoc tests should only be conducted when the ANOVA yields a non-significant resultYour company manufactures plastic wrap for food storage. The tear resistance of the wrap, denoted by X, must be controlled so that the wrap can be torn off the roll without too much effort but it does not tear too easily when in use. In a series of tests (see data table below), 15 rolls of wrap are made under carefully controlled conditions and the tear resistance of each roll is measured. The results are used as the basis of a quality assurance specification. If X for a subsequently produced roll falls more than two standard deviations away from the test period average, the process is declared out of specification and production is suspended for routine maintenance.
