Explanation / Answer

1.

There is no coefficient of the freshers given in the model. So it impossible to tell the test score for fresheres. The correct option is

a. none of the above (impossible to tell)

2.

The coefficient for juniors is 0.06 and the intercept is 0.48. So the test score is 0.48 + 0.06 = 0.54.The correct option is

d. 0.54

3.

The coefficient of seniors is -0.003 and the intercept parameter is 0.48. The test score for senior is 0.48 - 0.003 = 0.477 = 0.48 (rounded to two decimal places).

The correct option is

d. 48

4.

The coefficient of sophomores is -0.1 and the intercept parameter is 0.48. The test score for sophomore is 0.48 - 0.1 = 0.38

The correct option is

d. 0.38
