The following equation describes the median housing price in a community in terms of amount ofpollution (nox for nitrous oxide) and the average number of rooms in houses in the community (rooms):log(price) = Bo + B1 log(nox) + B2rooms + u(a) Why might nox (or more precisely, log(nox)) and rooms be negatively correlated? If this is the case, does thesimple regression of log(price) on log(nox) produce an upward or a downward biased estimator of ß,?Using the data in HPRICE2, the following equations were estimated:log(price)= 11.71 – 1.043 log(nox), n = 506, R².264.log(price)= 9.23 – .718 log(nox) + .306 rooms, n = 506, R² = .514.(b) Is the relationship between the simple and multiple regression estimates of the elasticity of price withrespect to nox what you would have predicted, given your answer in part (a)? Does this mean that -.718is closer to the true elasticity than -1.043?

Answered: the following equations were estimated:…

A standardized exam's scores are normally distributed. In a recent year, the mean test score was 1471 and the standard deviation was 318. The test scores of four students selected at random are 1910, 1210, 2210, and 1370. Find the z-scores that correspond to each value and determine whether any of the values are unusual. The z-score for 1910 is (Round to two decimal places as needed.)
