Hello,

Please help with the attached questions and explain your answer. Thanks!

1. A ECON 36 instructor believes that the average quiz score is a good predictor of final exam score. A random sample of 10 students produced the following data where x is the average quiz score and y is the final exam score. x y 72 72 96 98 55 50 65 70 100 96 50 60 85 83 70 75 74 77 85 87 a. Find an equation of the least squares regression line. b. Based on the equation from part (a), what is the predicted final exam score if the average quiz score is 80? 2. A study of 10 different weight loss programs involved 200 subjects. Each of the 10 programs had 20 subjects in it. The subjects were followed for 12 months. Weight change for each subject was recorded. We want to test the claim that the mean weight loss is the same for the 10 programs. a. Complete the following ANOVA table with sum of squares, degrees of freedom, and mean square. Source of Variation Sum of Squares (SS) Factor (Between) Error (Within) Total 53.6 553.05 Degrees of Freedom (df) Mean Square (MS) 199 N/A b. Determine the test statistic c. Determine the P-value. d. Is there sufficient evidence to support the claim that the mean weight loss is the same for the 10 programs at the significance level of 0.05? Explain
