A sample of 40 women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.238 and the equation of the regression line is y-hat=18.2+0.95x , where x represents height. The mean of the 40 pulse rates is 74.4 beats per minute. Find the best predicted pulse rate of a woman who is 68 inches tall. Use a significance level of 0.01.
