Below are the ages of six patients with blood pressure problems. Subject Age, x (independent) Pressure, y (dependent) A 43 128 B 48 120 C 56 135 D 61 143 E 67 141 F 70 152 Use this data to answer these six questions: a. Find the P-value and the significance level of ̱̱ =0.05. To four decimal places. Round to 4 decimal places. b. Find the critical value method obtained from the table for ̱̱ =0.05. To three decimal places. Round to three decimal places. c. What is the correlation coefficient? Round to 4 decimal places. d. Is there a correlation or no correlation. e. If there is correlation, determine the equation of the regression line. Use y-hat in your equation. Round slope and y-intercept to two decimal places. f. What is the best estimate of pressure for someone who is 65 years old? Round to the nearest tenth.

The data below are ages and systolic blood pressures (measured in millimeters of mercury) of 9 randomly selected adults. Age, x: 38, 41, 45, 48, 51, 53, 57, 61, 65 Pressure, y: 65, 75, 60, 80, 66, 78, 85, 90, 90 (A) (6 points) Determine the linear correlation coefficient between the age and systolic blood pressure. Show your work. (B) (4 points) Does a linear relationship exist between the age and systolic blood pressure? Justify your answer. (C) (7 points) Find the equation of the regression line for the given data. Show your work. (D) (5 points) What would be the predicted systolic blood pressure if the age was 60? Is this a reasonable question? Justify your answer.
