It is calculated by dividing an individual's weight (in kilograms) by the square of their height (in meters). A small sample was drawn from the population of UWC students to determine the effect of exercise on BMI score. Given the following table, find the constant and slope parameters of the sample regression function of BMI = f(Weekly exercise hours). Interpret the two estimated parameter values.
