Question

A sample of TO women is oblairned, and their heights (in inches) and pulse rates (in beats per minule) are measured. The lirear corelation coefticient is 0 244 and the equation of the regression line is 67r, tall LS 175+0870, where x represents height The mean ot the 70 heights is 62.9inadthe mean oftho 70 pube rates is 73 7 beats per minute Findthe best prodded pulso rate or a woman who Click the icontoviewtho crtical values the Pearson correlation coefficent The betd prodicted puise rate of a woman who is 67 in tall sbeats per minute beats per " nuto (Type an inbeer or decimal eounded to two decimal places as needed) Enter your ansae in te nwer box and then cick Chack Answer A parts showing

Explanation / Answer

For n = 70 and 0.01 significance level,

r = 0.305

Since the given correlation coefficient is less than this value, we can conclude that there is no significant linear relationship between these two variables.

Hence,

Best predicted pulse rate = Average pulse rate of 70 women = 73.7 beats per minute
