Use the dаtа set here fоr this prоblem. а) What is the median оf X2? [a_median]. b) What is the standard deviation of Y? [b_sd]. c) Construct scatterplots of the X variables against Y. T/F: there appears to be a positive relationship between Y and X3. [c_TRUE]. d) Regress Y on X1, X2 and X3. What is the R2 for this regression? [d_r2]. e) Examine the default residual plots in R. Are there any influential observations? [e_no]. f) Obtain the standardized residuals. Conduct a test of the assumption that these residuals are normally distributed. Use the test covered in this class. What is the test statistic for this test? [f_SWstat]. g) Based on this test do you conclude that the errors are approximately normally distributed or that they are not normally distributed? [g_normal]. h) Perform a Box-Cox analysis. Which value for lambda is most appropriate? [h_lambda] i) Apply the transformation and rerun the regression. That is, run a new regression using the transformed variable based on part (h). What is the estimated coefficient on X1 in this regression? [i_pt5189]. j) For the regression in part (i) with the transformed variable, test the hypothesis
