Use the tоy dаtа set here fоr this prоblem. а) What is the median of X2? [a_49pt41]. b) What is the standard deviation of Y? [b_5pt46]. c) Construct a histogram of Y. Use the default number of breaks; there should be 7 bins or groupings in your graph. T/F: the histogram has roughly a bell shape which is consistent with Y being normally distributed. [c_T]. d) Run a regression with Y as the dependent variable and X1, X2, X3, and X4 as the explanatory variables. What is the estimated coefficient on X1? [d_pt54449]. e) What the 90% confidence interval for the coefficient on X2? [e_90pctinterval]. f) What is the 90% confidence interval for the conditional mean when X1=45, X2=51, X3=49 and X4=52? [f_interval]. g) Examine the default plots for the regression model in R. Based on the Q-Q plot it appears that (i) the errors are normally distributed, (ii) the errors are not normally distributed, (iii) the dependent variable is normally distributed, (iv) the dependent variable is not normally distributed. [g_i]. h) Using alpha of 0.05 do you reject or fail to reject the hypothesis that the coefficient on X4 is 0? [h_fail]. i) Test the hypothesis,
