A research hospital did a study on the relationship between stress and diastolic blood pressure. The results from eight patients are given in the table below. Blood pressure values are measured in the mL of mercury. Stress test score, x 55 62 58 78 92 88 75 80 Blood pressure, y 70 85 72 85 96 90 82 85 a) Use the points (55, 70) and (92, 96) to find a linear model that will predict the blood pressure of a patient for a given stress test score. Round the slope to the nearest ten-thousandth. b) Use your linear model to estimate the diastolic blood pressure of a person whose stress test score was 85. Round to the nearest whole number.
