x 63 63 67 65 61 63 61 64 62 63 y 63 65 65 65 64 64 63 62 63 64 x 64 63 64 64 63 67 61 65 64 65 66 y 64 64 65 65 62 66 62 63 66 66 65

a. Draw two dotplots using the same scale and showing the two sets of data side by side.

b. What can you conclude from seeing the two sets of heights as separate sets in part a? Explain.

c. Draw a scatter diagram of these data as ordered pairs.
