Answer #1

The point estimate for the intercept for House B is obtained from the given coefficients for the variables as 1.3023. Therefore 1.3023 is the required point estimate for the intercept for House B here.

It is already given in the given table of coefficients for the regression here. The regression equation here is given as:

Y = 3.456 + 0.4264*Age + 1.3023*HouseB + 1.5384*HouseC + 1.3546*Age:HouseB - 0.2845*Age:HouseC

Therefore 1.3023 is the required point estimate value here.

13. Interpreting the intercept in a simple linear regression model is: * (A) reasonable if the sample contains values of x around the origin. (B) not reasonable because researchers are interested in the effect of a change in x on the change in y. (C) reasonable if the intercept’s p-value is less than 0.05. (D) not reasonable because it is always meaningless. 14. Which of the following is NOT one of the assumptions necessary for simple linear regressions?: * (A)...
