The partially completed analysis of variance table given below is taken from the article, "Power and Status, Exchange, Attribution, and Expectation States (Small Group Research)." The experimenters investigated the effects of power and knowledge on one's emotional reaction in a study involving 52 students selected from a large private university. Each of the factors was run at two levels, with 13 subjects at each of the four different factor combinations. Source of Variation Power Knowledge Interaction Error Total ANOVA SS 0.2800 1.2600 3.1400 4.7600 df 1 1 1 48 51 MS F Complete the ANOVA table. Step 2 of 4: Calculate the F-statistic for the hypothesis test of interaction between the variables Power and Knowledge. Round your answer to four decimal places.

A school district has four schools, six class in from each school were randomly selected and the number of students in the class were recorded. Test the claim that at least one school has a different class size at a 0.10 level of significance.

1. Conduct a two-sample t-test at a 1% level of significance to find out if the U.S. stock returns significantly outperform the U.S. corporate bond returns using the monthly data covering the sample period 1980-2019. Please explain the hypothesis and how to use the summary to answer the question.
A criminologist was interested in whether there was any disparity in sentencing. She selected at random of 24 drug convictions for cocaine distribution and compared the prison terms given by two judges as below. Judge1 Judge2 7 5 7 6 6 4 5 5 2 5 5 5 7 4 6 6 5 5 7 5 10 4 7 5 From performing a hypothesis test to determine if judge1 differs from judge2 in the mean of sentence years, what is the obtained t? (Round off to three decimal places if necessary)

(b) Is the sample size large enough for the inference in part (a) to be valid? (c) Is it necessary to further describe the relationship between the need for item pricing and age? Explain briefly. If yes, further describe the relationship by providing an appropriate plot.
