Answer #1

(A) The model here is given by,

Here the slope coefficient is 120.5, which means that on one unit increase in the regressor log(X), the response Y increases by 120.5 units on average. If X = 10, then the estimate of Y is,

(B) The model here is given by,

Here the slope coefficient is 0.019, which means that on one unit increase in the regressor X, the response log Y increases by 0.019 units on average. If X = 10, then the estimate of log Y is,

(C) The model here is given by,

Here the slope coefficient is 3.5, which means that on one unit increase in the regressor log X, the response log Y increases by 3.5 units on average. If X = 10, then the estimate of log Y is,
