Explanation:

Step1: Analyze the shape of the histogram

The histogram has a similar number of months on the left - hand side (0 - 1 inches and 1.01 - 2 inches) and the right - hand side (4.01 - 5 inches and 5.01 - 6 inches) with lower counts in the middle (2.01 - 3 inches and 3.01 - 4 inches). This indicates symmetry.

Step2: Identify the intervals with higher frequencies

The higher frequencies are in the intervals 0 - 1 inches and 5.01 - 6 inches, which means the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.

Answer:

The data is symmetrical, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.
