To find the difference between the maximum and minimum number of home runs hit by Babe Ruth from 1926 to 1930, we first need to identify the maximum and minimum values from the heights of the bars:
- 1926: 47 home runs
- 1927: 60 home runs (this is the maximum)
- 1928: 54 home runs
- 1929: 46 home runs
- 1930: 48 home runs
From this data, the maximum number of home runs is 60 (in 1927) and the minimum number of home runs is 46 (in 1929).
To find the difference:
\[ \text{Difference} = \text{Maximum} - \text{Minimum} = 60 - 46 = 14 \]
Therefore, the maximum number of home runs hit exceeds the minimum number by 14.
