The Blood Pressure-Weight data set contains blood pressure and weight readings of 20 cardiac patients. Using Weight as the predictor variable, fit a simple linear regression model and save the residuals. Then use the residuals to calculate both the Shapiro-Wilk and the Anderson-Darling p-values needed to test the assumption that those residuals are normally distributed. (Round your answer to three decimal places; add trailing zeros as needed.) The Shapiro-Wilk p-value = Incorrect answer: 0.090 The Anderson-Darling p-value = Incorrect answer: 0.126 270 236 210 142 280 272 160 220 226 242 186 266 206 318 294 282 234 224 276 282 360 310 280 278 288 288 244 236

The weight and systolic blood pressure of 26 randomly selected males in the age group 25 to 30 are shown in the following table. Assume that weight and blood pressure are jointly normally distributed. Find a regression line relating systolic blood pressure to weight. Test for significance of regression using α = 0.05. Estimate the correlation coefficient.

The data show systolic and diastolic blood pressure of certain people. Find the regression equation, letting the first variable be the independent (x) variable. Find the best predicted diastolic pressure for a person with a systolic reading of 146. Use a significance level of 0.05. Systolic: 117, 134, 150, 113, 138, 113, 144, 145 Diastolic: 85, 74, 86, 55, 75, 80, 106, 84 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.) What is the best predicted value? y^ ≈ [ ] (Round to one decimal place as needed.)
