Julie wants to compare the heights of two types of tomato plants, Type A and Type B, for her vegetable garden. She thinks the mean height of Type A plants will be greater than the Type B, but she doesn’t know how much greater. She also wants to know about the variability of the heights of each plant type. She uses the data she collects to generate the list below. Part A. Create two dot plots using the same scale to help Julie compare her data sets.

Part B. Julie observes that there is some overlap in the sets. Calculate the mean height of each of these tomato plants. Round your answers to the nearest whole number. What is the difference in the mean height of these tomato plants?

Part C. Compare the variability of the sets. Look at the mean heights and the variability of the sets to make a comparison statement about the two sets.
