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
