The linear correlation coefficient is 0.285 and equation of regression line is y=17.8+0.910x, where x represents height. The mean of 60 heights is 62.8 inches and mean of the 60 pulserate is 72.8 beats per minute. Determine the best predicted pulse rate of a woman is 66 inches tall. Use the significance level of a=0.01
