In an experiment conducted by one of this book's authors, 19 students were asked to estimate (in millions) the population of Canada, which was about 30 million at that time. Before they made their estimates, ten of the students (Group 1) were told that the population of the United States was about 290 million at that time. Nine of the students (Group 2) were told that the population of Australia was roughly 20 million at that time. The estimates for the population of Canada given by the students in each group were:
Group 1: 2, 30, 35, 70, 100, 120, 135, 150, 190, 200
Group 2: 8, 12, 16, 29, 35, 40, 45, 46, 95
a. Find the five-number summary for Group 1.
b. Find the five-number summary for Group 2.
c. Compare the values of the range for the two groups.
d. Draw a boxplot that compares the two groups. Refer to Figure 2.14 (p. 34) for guidance.
