a. In an IV regression model with one endogenousregressor, X, and two instruments, Z1 and Z2, thevalue of the J-statistic is J = 18.2. This suggests thatE(ui |Z1i, Z2i) = 0. Is it true or false?b. Suppose that a true population IV regressionmodel contains one endogenous regressor, X, oneexogenous regressor, W, and one instrument, Z.Assume that data on W are not available and themodel is estimated omitting W from the regression.Suppose that Z and W are uncorrelated. Then the IVestimator is inconsistent. Is it true or false?

A researcher developed a regression model to predict the cost of a meal based on the summated rating (sum of ratings for food, decor,and service) and the cost per meal for 12 restaurants. The results of the study show that b1=1.4379 and Sb1=0.1397. a. At the 0.05 level of significance, is there evidence of a linear relationship between the summated rating of a restaurant and the cost of a meal? b.

The Update to the Task Force Report on Blood Pressure Control in Children [12] reported the observed 90th per-centile of SBP in single years of age from age 1 to 17 based on prior studies. The data for boys of average height are given in Table 11.18.
