Question 2 The distribution of number of people per household is O not normally distributed because it is discrete and skewed O normally distributed O normally distributed even though it is discrete O normally distributed even though it is skewed Question 3 Assuming CR1-CR3 plus a large enough sample, the 95% confidence interval for B, in the schools example is O (-2.82, -1.40) None of these 1.96 O -2.11 Question 4 Consider the two regression models Model 1: Y; = Bo + E; %3D Model 2: Y, = B, + B1 X1; + B2 X + Ei %3D You wish to test the null hypothesis Ho B = 0 and B2 0. You compute the Wald statistic: R-Rvil W = (1-) N-Kalt- O R2null is an R-squared, but not from either Model 1 or Model 2 O R2alt is the R-squared from Model 2 and R2null is the R squared from Model 1 O R2alt is the R-squared from Model 1 and R2null is the R squared from Model 2 O R2alt is an R-squared, but not from either Model 1 or Model 2
