Assignment:
Use the given data to find the best predicted value of the response variable. Be sure to follow the prediction procedure summarized in Figure below.
Height and Pulse Rate A sample of 40 women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.202 and the equation of the regression line is yˆ= 18.2 + 0.920x , where x represents height (based on data from the National Health Examination Survey). The mean of the 40 heights is 63.2 in. and the mean of the 40 pulse rates is 76.3 beats per minute. Find the best predicted pulse rate of a woman who is 70 in. tall.
