Question 1

True or False.

The rejection of the null hypothesis in a global F-test means that the model is the best model for providing reliable estimates and predictions.
◦ True
◦ False

Question 2

As part of a study at a large university, data were collected on n = 224 freshmen computer science (CS) majors in a particular year. The researchers were interested in modeling y, a student's grade point average (GPA) after three semesters, as a function of the following independent variables (recorded at the time the students enrolled in the university):

      x1 = average high school grade in mathematics (HSM)
      x2 = average high school grade in science (HSS)
      x3 = average high school grade in English (HSE)
      x4 = SAT mathematics score (SATM)
      x5 = SAT verbal score (SATV)

A first-order model was fit to data.

Give the null hypothesis for testing the overall adequacy of the model.
◦ H0: β0 = β1 = β2 = β3 = β4 = β5 = 0
◦ H0: β1 = 0
◦ H0: β1 = β2 = β3 = β4 = β5 = 0
◦ H0: β0 + β1x1 + β2x2 + β3x3 + β4x4 + β5x5 = 0
