Instructor: Charles Conrad Course: STATISTICS - 7 WEEK - FALL 2017 Student: keith holden Date: 10/9/17 Assignment: Chapter 10.2 Homework 7. Listed below are systolic blood pressure measurements (in mm Hg) obtained from the same woman. Find the regression equation, letting the right arm blood pressure be the predictor (x) variable. Find the best predicted systolic blood pressure in the left arm given that the systolic blood pressure in the right arm is 90 mm Hg. Use a significance level of 0.05. Right Arm 101 100 92 77 78 Left Arm 174 168 140 141 143 Click the icon to view the critical values of the Pearson correlation coefficient r 1 The regression equation is y = (Round to one decimal place as needed.) + x. Given that the systolic blood pressure in the right arm is 90 mm Hg, the best predicted systolic blood pressure in the left arm is mm Hg. (Round to one decimal place as needed.) 1: Critical Values of the Pearson Correlation Coefficient r Critical Values of the Pearson Correlation Coefficient r n = 0.05 = 0.01 4 0.950 0.990 5 0.878 0.959 6 0.811 0.917 7 0.754 0.875 8 0.707 0.834 9 0.666 0.798 10 0.632 0.765 11 0.602 0.735 12 0.576 0.708 13 0.553 0.684 14 0.532 0.661 15 0.514 0.641 16 0.497 0.623 17 0.482 0.606 18 0.468 0.590 19 0.456 0.575 20 0.444 0.561 25 0.396 0.505 30 0.361 0.463 35 0.335 0.430 40 0.312 0.402 45 0.294 0.378 50 0.279 0.361 60 0.254 0.330 70 0.236 0.305 80 0.220 0.286 90 0.207 0.269 100 0.196 0.256 NOTE: To test H0 : = 0 against H1 : 0, reject H0 if the absolute value of r is greater than the critical value in the table
