Answer:
The difference in the heights of the bars will not appear as great.
Step-by-step explanation:
Since we are asked what the difference would be if the scale on the y-axis beings with 0, this tells us that the current graph does <em>not</em> start at 0.
Comparing two histograms of the same data, one that starts at 0 and one that does not start at 0, we will see that the heights of the bars on the graph that does not start at 0 seem to be much more different.
This is because when we compare, for example, a height from 20 to 50, where the next goes from 20 to 30 (20 difference compared to the actual height of the highest bar being 30), the differences in heights are much more pronounced than they would be if the bars went from 0 to 50 and from 0 to 30 (20 difference compared to the highest of 50).
