A) To be able to estimate the age at which circulatory incidents are likely to occur, given the cholesterol level.
B) To determine how well the data fit the theoretical framework
C) To calculate the strength of the relationship between cholesterol levels and circulatory incidents
D) To determine whether there is a linear relationship between cholesterol levels and circulatory incidents
E) To derive the formula for the line of best fit
F) To obtain information from which to construct a better scatter plot
