Below is a partial multiple regression computer output based on a quadratic regression model to predict student enrollment at a local university.The dependent variable is the annual enrollment given in thousands of students,the independent variable X is the increase in tuition stated in thousands of dollars per year,and X² is the square of tuition increase given in squared thousands of dollars per year.
Interpret $\beta$ ₀ (the y intercept)and $\beta$ ₁ (the $\beta$ coefficient for the X variable).Does the parabola open upward or downward? Why?
