10.3.7 A sample of 50 women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.206 and the equation of the regression line is y = 17.8+0.860x, where x represents height. The mean of the 50 heights is 83.8 in and the mean of the 50 pulse rates is 72.3 beats per minute. Find the best predicted pulse rate of a woman who is 67 in tall. Use a significance level of a = 0.01. Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted pulse rate of a woman who is 67 in tall is beats per minute.
