The heights (inches) and foot lengths (cm) of 33 college men are shown in the following table. (These data are in the dataset height foot on the companion website.)
a. Draw a scatterplot with y = foot length (cm) and x = height (inches). Does the relationship appear to be linear? Are there any outliers? If so, do you think the outliers are legitimate data values?
b. Use statistical software or a calculator to calculate the correlation between height and foot length. If heights were converted to centimeters, what would be the correlation between height and foot length?
c. If there are any outliers, remove them and recalculate the correlation. Describe how the correlation changed from part (b).
