Amultiple regression model is developed by a lecturer in order to study how students fare in their end-of-year exams. the dependent variable is the score a student achieves in the end-of-year exam (y) and this variable is modeled against two independent variables: their score in the mid-year exam (x1) and the number of hours they spent studying for the end-of-year exam (x2).

y = ? 0 + ? 1x1 + ? 2x2 + ?

a sample of 60 students is collected. for each student, the student's score in the mid year exam, the number of hours they studied, and their score in the end-of-year exam are recorded. the following regression equation was developed:

y^ = 5 + 0.8x1 + 0.4x2

a t test is to be conducted in order to assess the significance of mid-year score in predicting end-of-year score. select whether the following statements about the test are true or false:
