Suppose that the true relationship between y; and ; is as follows,Yi = B₁ + B₂xi + UiThe error term satisfies that E[u₂] = 0 and Var(u) = 1. You findanother variable zi whose sample correlation with x is equal to -1.Select correct statement(s).Because the correlation is equal to -1, we have %₁ = -₂.O If we add z; in the regression model along with ;, R² will be increased.Adding z; along with in the regression model is not plausible becauseof the perfect multicollinearity.O If we estimate the model y₁ = a₁ + a2%; + e₁, the estimator of a2 willbe equal to -3₂, where B₂ is the OLS estimator of 32

A random sample of n1 = 20 winter days in Denver gave a sample mean pollution index x1 = 43. Previous studies show that ?1 = 11. For Englewood (a suburb of Denver), a random sample of n2 = 18 winter days gave a sample mean pollution index of x2 = 36. Previous studies show that ?2 = 15. Assume the pollution index is normally distributed in both Englewood and Denver. Do these data indicate that the mean population pollution index of Englewood is different (either way) from that of Denver in the winter? Use a 1% level of significance. a) What is the value of the sample test statistic? (Test the difference ?1 − ?2. Round your answer to two decimal places.)b) Find (or estimate) the P-value. (Round your answer to four decimal places.)

In a sample there are 3 male dogs and 3 female dogs. These dogs are couples such that the weight of the ith dog, and the Fi measures the weight of the ith dogs girlfriend. The correlation between M and F is exactly 1 and when the data points are graphed the slope of them are 1. Is it possible for some of these dogs to weight more than their female couple, while other dogs weight less then their female couple? And is it possible that all of the male dogs have couple female dogs that are all shorter than them?
