The data show systolic and diastolic blood pressure of certain people. Find the regression equation, letting the systolic reading be the independent (x) variable. If one of these people has a systolic blood pressure of 137 mm Hg, what is the best predicted diastolic blood pressure? Systolic Diastolic 122 134 143 140 135 113 110 145 62 71 80 80 100 59 82 105 Click the icon to view the critical values of the Pearson correlation coefficient r. What is the regression equation? y=+x (Round to two decimal places as needed.) Critical Values of the Pearson Correlation Coefficient r X What is the best predicted diastolic blood pressure? y=(Round to one decimal place as needed.)
