For example: John recorded the number of houses that were decorated with holiday lights on different blocks in his neighborhood.

Which was the most common interval for the number of decorated houses?

**Solution:**

From the above histogram, we get the following information:

Number of blocks in the interval 0-4: 2

Number of blocks in the interval 5-9: 8

Number of blocks in the interval 10-14: 5

Number of blocks in the interval 15-19: 1

8 is the greatest number among 2, 8, 5, 1.

Therefore, the most common interval for the number of decorated houses is 5-9.
