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 ofwomen? Use a significance level of
alphaαequals=0.010.01.
