A sample of 100


100 women is​ obtained, and their heights​ (in inches) and pulse rates​ (in beats per​ minute) are measured. The linear correlation coefficient is 0.281


0.281 and the equation of the regression line is ModifyingAbove y with caret equals 18.1 plus 0.910 x



y=18.1+0.910x​, where x represents height. The mean of the 100


100 heights is 63.6


63.6 in and the mean of the 100


100 pulse rates is 72.3


72.3 beats per minute. Find the best predicted pulse rate of a woman who is 68


68 in tall. Use a significance level of alpha equals 0.01


α=0.01.
