The partially completed analysis of variance table given below is taken from the article, "Power and Status, Exchange, Attribution, and ExpectationStates (Small Group Research)." The experimenters investigated the effects of power and knowledge on one's emotional reaction in a studyinvolving 52 students selected from a large private university. Each of the factors was run at two levels, with 13 subjects at each of the fourdifferent factor combinations.Source of VariationPowerKnowledgeInteractionErrorTotalANOVASS0.28001.26003.14004.7600df1114851MSFComplete the ANOVA table.Step 2 of 4: Calculate the F-statistic for the hypothesis test of interaction between the variables Power and Knowledge.

n engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 160 engines and the mean pressure was 7.7 pounds/square inch (psi). Assume the population variance is 0.36. If the valve was designed to produce a mean pressure of 7.8 psi, is there sufficient evidence at the 0.01 level that the valve performs below the specifications? Step 2 of 3: Find the P-value for the hypothesis test. Round your answer to four decimal places.
