This relative frequency histogram shows the distribution of average daily temperatures (in degrees Fahrenheit) for a town over the course of 5 years.
Match each temperature interval with the proportion of days over the 5 years whose average temperature fell in that interval.

Two curves representing normal distributions are shown. Does the solid curve or dashed curve have a greater standard deviation? Explain how you know.
Here are 2 distributions.
How does the mean of set A compare to the mean of set B? Explain your reasoning.
Which distribution is symmetric?
Clare is designing an experimental study. She says that it is important to randomly assign people to random groups in an experimental study because this helps reduce the likelihood of grouping subjects into groups that may differ on some characteristic that is related to the response of interest.
Do you agree with Clare? Explain your reasoning.
