1. The regression equation (i.e. least squares line) y = .97x + 31.85 describes the relationship between blood sugar levels (x) and cholesterol levels (y) for 8 different patients. (a) For this problem, the correct interpretation of the slope is: A) For each additional level of sugar, the cholesterol decreases by 31.85. B) For each additional .97 levels of sugar, the cholesterol increases by 31.85. C) For every additional level of cholesterol, the sugar level increases by .97. D) For...

we use the form y a + bx for the least-squares line. In some computer printouts, the least-squares equation is not given directly. Instead, the value of the constant a is given, and the coefficient b of the explanatory or predictor variable is displayed. Sometimes a is referred to as the constant, and sometimes as the intercept. Data from a report showed the following relationship between elevation (in thousands of feet) and average number of frost-free days per year in...
