The regression equation for for the association between BMI and total cholesterol level is:
y = 28.07 + 6.49x
A.) Suppose a participant has a BMI of 26. What would we estimate the total cholesterol to be?
B.) Suppose two individuals have a mean BMI that differs by 3 units. What is the estimated difference in total cholesterol.
C.) What ranges of BMI should the equation be used to predict total cholesterol?
Use the given data to find the best predicted value of the response variable.
Eight pairs of data yield r = 0.742 and the regression equation y = 55.8 + 2.79x. Also, y = 71. 125. What is the best predicted value of y for x = 8.
