Question
Please help! It would be greatly appreciated!
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 0.236 and the equation of the regression line is y = 17.5 + 0.930x, where x represents height. The mean of the 40 heights is 63.5 in and the mean of the 40 pulse rates is 72.9 beats per minute. Find the best predicted pulse rate of a woman who is 74 in tall. Use a significance level of ?=0.05. ewe 40 Click the icon to view the critical values of the Pearson correlation coefficient r.

Enter your answer in the answer box.Explanation / Answer
Given the regression line of y on x is
Y = 17.5 + 0.930 X
Given x = 74 inches then
Y = 17.5 + 0.930 (74)
Y = 86.32 beats per minute
