A dоctоr wаnted tо determine whether there is а relаtionship between a male’s age and his HDL cholesterol level. The sample below represents ten males selected at random. Data Table Age, x 38 42 46 32 55 52 61 66 26 38 HDL, y 57 54 34 56 35 40 42 47 44 62 Calculate the value of the correlation coefficient (round to three decimal places). [r] Is there a significant correlation between x and y? (yes or no) [sign] Calculate the value of the coefficient of determination (round to three decimal places). [r-sq] Find the equation of the least-squares regression line (round each coefficient to three decimal places). y = [a] + [b]x Predict the HDL level for a 42-year-old male (round to the same number of decimal places as y).
