1. Be sure to use the original, unsorted data for this problem. Make a scatterplot on your calculator using the men's/women's heights as the x-variable and men's/women's shoe size as y-variable.
a. Is there an increasing or decreasing pattern? Explain what that means in terms of height and shoe sizes.
b. Calculate the correlation coefficient, r. (3 decimal places)
c. Calculate the regression equation. (Round to 3 decimal places.)
d. Use the equation to predict the shoe size (to nearest ½ size) for a man/woman who is 5 feet 7 inches tall.
