Draw a scatter diagram of the data, treating age as the explanatory variable. What type of relation, if any, appears to exist between age and HDL cholesterol? Determine the least-squares regression equation from the sample data Assuming the residuals are normally distributed, test whether a linear relation exists between age and HDL cholesterol levels at the α=0.01 level of significance.
