The heights​ (in inches) and pulse rates​ (in beats per​ minute) for a sample of

2525

women were measured. Using technology with the paired​ height/pulse data, the linear correlation coefficient is found to be

0.3880.388.

Is there sufficient evidence to support the claim that there is a linear correlation between the heights and pulse rates of​women? Use a significance level of

alphaαequals=0.010.01.
