Question

the amount of rainfall each month over the past four years is shown below. which statement must be true according to the histogram? monthly rainfall over the past four years the data is skewed, showing that the majority of the monthly rainfall amounts was between 2.01 and 4 inches. the data is skewed, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches. the data is symmetrical, showing that the majority of the monthly rainfall amounts was between 2.01 and 4 inches. the data is symmetrical, showing that the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.

Explanation:

Step1: Analyze the shape of the histogram

The histogram is not symmetric. The bars on the left - hand side (0 - 1 and 1.01 - 2) and right - hand side (4.01 - 5 and 5.01 - 6) are taller than the bars in the middle (2.01 - 3 and 3.01 - 4), which means the data is skewed.

Step2: Determine the range with majority of data

The taller bars are in the ranges 0 - 1 and 5.01 - 6, so the majority of the monthly rainfall amounts was less than 2.01 or greater than 4 inches.

Answer:

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