Part 3
c. Compare and interpret the results.
A.
Since the intervals overlap, the populations appear to have amounts of variation that are not substantially different.
B.
Since the intervals do not overlap, the populations appear to have amounts of variation that are not substantially different.
C.
Since the intervals do not overlap, the populations appear to have different amounts of variation.
