A sample of 28 women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.209 and the equation of the regression line is y=18.4+0.870x, where x represents height. The mean of the 28 heights is 63.3 in and the mean of the 28 pulse rates is 72.9 beats per minute. Find the best predicted pulse rate of a woman who is 75 in tall.
