Question

Question 2 1 pts Suppose that we wish to built the following multiple regression model: Ý; = ßo + Ê, Xi1 + ,Xj2 where Y = mathematics exam score, X 1 =number of hours spent studying, X 2 =number of hours spent playing video games. Suppose we know that the number of hours spent studying is directly inversely proportional to the number of hours spend playing video games. Which of the following would be true, We cannot obtain the coefficients because the least squares solution does not exist. The coefficient for X1 must have a positive sign, and for X a negative sign. Both coefficients to be the same distance from the constant, one above and the other below. The coefficient for X2 must have a positive sign, and for X1 a negative sign.

Answer 1

} = R + Big + Pa xiz poopostional to the no. of houps spend play- Sa Given following multiple gegoession model is 1 when yo mathematic exam scose X; - number of houps spent studying, X = number of hours spent spent playing video game Suppose we know. that the number -ing video games based on above data of houps spend studying is disectly inversly So option A We commot obtain the coefficiente because the least squares Solution is tove. does not exist So option (A) is
