The blood pressures, p mmHg, and the age t years of 7 hospital patients are shown in the table below: Patient t A B 42 D E F G 74 48 35 56 26 60 98 130 120 88 182 80 135 a. Find the product correlation for these data. b. Interpret the correlation coefficient. c. Draw the scatter diagram of blood pressure against age for the 7 patients. d. Find the equation of the regression line of p on t. e. Use the regression line to estimate the blood pressure of a 40-year-old patient.
