Question

A sample of women is obtained and their heights (in inches) and pulse rates in beats per minute) are measured. The Bear correction coefficient is 0.227 and the equation of the regression is 17.6 + 0.890x, where x represents height. The mean of the 80 heights is 63.4 in and the mean of the 80 pulse rates is 77.4 beats per minute. Find best predicted pulse of a woman who is 98 in tall. Use a significance level of alpha = 0.01. Click the icon to view the critical values of the Pearson correlation coefficient t. The best predicted pulse a woman who is 68in tall is beats per minute. (Type an integer decimal rounded to two decimal places as needed)

Explanation / Answer

for abvoe linear regression equation Yhat=17.6+0.890x

hence ar x=68 best predicted pulse rate =17.6+0.890*68=78.12
