  1. A farmer was interested in the yield produced by his crop. The graph shows the number of seeds of different masses in the crop yield.
A histogram showing the distribution of seed mass in grams against the number of seeds. The x-axis is 'Seed mass / g' with ranges from 0.0-1.0 to 8.1-9.0. The y-axis is 'Number of seeds' ranging from 0 to 60. The distribution appears somewhat bell-shaped, peaking around 3.1-4.0 and 4.1-5.0 g.
