6) When looking at the shape of the distribution using a histogram, a distribution is skewed to the
x x x x x x x x x x x x x x x x



right when the left tail is shorter than the right tail.
x x x x x x x x x x x

9) The cumulative frequency for a class will always be at least as large as the cumulative
x x x x x x x x x x x x x x x



frequency for any class with a smaller upper boundary.
x x x x x x x x x
