A sample of 80 women is​ obtained, and their heights​ (in inches) and pulse rates​ (in beats per​ minute) are measured. The linear correlation coefficient is 0.218 and the equation of the regression line is ŷ=17.9+0.950x​, where x represents height. The mean of the 80 heights is 63.3 in and the mean of the 80 pulse rates is 73.5 beats per minute. Find the best predicted pulse rate of a woman who is 72 in tall. Use a significance level of a= 0.01.

The best predicted pulse rate of a woman who is 72 in tall is ____ beats per minute.

​(Type an integer or decimal rounded to two decimal places as​ needed.)
