A sample of 70women isobtained, and their heights(in inches) and pulse rates(in beats perminute) are measured. The linear correlation coefficient is0.269 and the equation of the regression line isy = 18.2 + 0.920x,where x represents height. The mean of the 70heights is63.2 in and the mean of the 70pulse rates is73.6 beats per minute. Find the best predicted pulse rate of a woman who is 72 in tall. Use a significance level of=0.05
The best predicted pulse rate of a woman who is 72 in tall is_______beats per minute..
(Round to two decimal places asneeded.)
