Cоnsider dаtа оn X = Bаt (batting average) and Y = Wins (number оf wins) for n = 30 Major League Baseball teams for the 2010 regular season. We would like to examine the relationship between these two variables. Minitab output for a simple linear regression model for this data is as follows: Coefficients Term Coef SE Coef T-Value P-Value VIF Constant -44.6 45.7 -0.97 0.338 Bat 488 178 2.75 0.010 1.00 Model Summary S R-sq R-sq(adj) 9.93916 21.24% 18.43% Analysis of Variance Source DF SS MS F P Regression 1 745.97 745.969 7.55 0.010 Error 28 2766.03 98.787 Total 29 3512.00 Graphical residual analysis resulted in the following: A t-distribution probability calculation resulted in the following: Student’s t distribution with 28 DF P( X ≤ x ) x 0.975 2.04841 Using the fitted model to make a prediction at X = 0.260 resulted in the following: Prediction Fit SE Fit 95% CI 95% PI 82.3344 1.87848 (78.4865, 86.1823) (61.6145, 103.054) Use the Minitab output to answer the following questions. Type your answers to the questions in the text box below, making sure to reference the relevant part of the output in each answer. (7 points) Report the fitted simple linear regression equation for these data and what does the scatterplot say about the relationship between two variables? (8 points) What are your impressions of the plot of the residuals versus the fitted values and the normal probability plot of the residuals. What do the plots tell us about our fitted model? (8 points) Test whether there is a statistically significant linear relationship at a 5% significance level. For full credit you must report the hypotheses, F-statistic, the degrees of freedom, the p-value and a conclusion in the context of the problem. (8 points) Calculate a 95% confidence interval for the slope parameter. Include details of the calculation and interpret the interval. (5 points) Report a 95% prediction interval for the number of wins for a team with a batting average of 0.260 and interpret the interval. [There is no need to include details of the interval calculation.]
