Consider these data sets:

I: 1, 3, 2, 2, 5, 4, 4, 3, 3

II: 1, 2, 4, 1, 2, 5, 2, 5, 1, 5, 5, 3

(a) Find the mean and median for each set. Show your work.

(b) Find variance and standard deviation for each set. Show your work.

(c) Would you be surprised to hear someone claim that these data were drawn from the same population? (Hint: Draw a histogram for each set. Compare the shapes.)
