A professor is interested in understanding the factors on which the grades a student obtains in her final exam depends. She chooses the student's intelligence quotient (X₁), the grades obtained in the mid-term exam (X₂), the number of days the student was present in the class in the whole semester (X) as regressors. She randomly selects 120 students and estimates the following regression function: 9-65+1.23X,, +0.45X, 2.13X + where X₁X and X, denote the predicted value of grades obtained by the student, her intellegence quotient, the grades obtained by her in the mid-term exam, and the number of days she was present in the class in the whole semester, respectively She calculates the value of the regression R to be 0.78 The value of the adjusted R² (²) will be (Round your answer to two decimal places). Which of the following statements is not true about the A7 (Check all that apply) A The value of R is always greater than the given that the number of regressors remains the same in the regression equation. B. The value of increases when a new regressor is added to the regression equation. always lies between 0 and 1. can be gative c. The value of D. The value of R
