Is your overall satisfaction with your new pair of walking shoes correlated with the cost of the shoes? Satisfaction scores and prices were recorded for nine different styles and brands of men€™s walking shoes, with the following results:

a. Calculate the correlation coefficient r between price and overall score. How would you describe the relationship between price and overall score?

b. Use the applet called Correlation and the Scatterplot to plot the nine data points. What is the correlation coefficient shown on the applet? Compare with the value you calculated in part a.

c. Describe the pattern that you see in the scatterplot. Are there any outliers? If so, how would you explain them?
