Score: 0 of 1 pt 16 of 35 (7 complete) HW Score: 20%, 7 of 35 pts 10.3.7 Question Help A sample of 50 women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.224 and the equation of he regression line is y = 18.4 + 0.950 , w here x represents height. The mean the 50 heights s 3 and the mea o the pulse rates i 773 eats per minute. Find the best predicted pulse rate of a woman who is 72 in tall. Use a significance level of = 0.01 Click the icon to view the critical values of the Pearson correlation coefficient r. The best predicted pulse rate of a woman who is 72 in tall isbeats per minute. (Type an integer or decimal rounded to two decimal places as needed.)

Explanation / Answer

Given:

y = 18.4 + 0.95 * x

x = 72

y = 18.4 + 0.95 * 72

y = 86.8

So, pulse rate =86.8 beats per minute.
