A sample of

30

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

0.231

and the equation of the regression line is

y=17.8+0.920x,

where x represents height. The mean of the

30

heights is

63.5

in and the mean of the

30

pulse rates is

74.7

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

67

in tall.
