A scientist is studying the effect of different types of soll on the height of plants. All plants were of the
same type and were planted at the same time. The scientist randomly selected 50 plants grown in each of
5 different soil types and recorded the heights of the plants in centimeters. The box plots for the soil
samples are shown.
