The data below shows height (in inches) and pulse rates (in beats per minute) of a random sample of women. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the Pvalue using α=0.05 Is there sufficient evidence to conclude that there is a linear correlation between height and pulse rate?

What are the null and alternative hypotheses?
The linear correlation coefficient r is
The test statistic t is
The Pvalue is
Is there sufficient evidence to conclude that there is a linear correlation between the two variables?
A. Yes,because the Pvalue is greater than the significance level
B. No, because the Pvalue is greater than the significance level.
C. No, because the Pvalue is less than the significance level.
D. Yes, because the Pvalue is less than the significance level.
