Statistics

A sample of 80 women is obtained, and their heights ( in inches ) and pulse rates ( in beats per minute ) are measured. The linear correlation coefficient is 0.216 and the equation of the regression line is ^y= 17.9 + 0.940x, where x represents height. The mean of the 80 heights is 63.2 in and the mean of the 80 pulse rates is 73.1 beats per minute. Find the best predicted pulse rate of a woman who is 75 inches tall. Use a significance level of a=0.05.
