Question

the amount of rainfall each month over the past four years is shown below.
monthly rainfall over the past four years
which statement must be true according to the histogram?
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 histogram

Looking at the histogram, we can see that the bars are not symmetrically distributed. The data is skewed.

Step2: Check the majority of data

The majority of the bars (representing the number of months) are in the lower - rainfall intervals (0 - 1, 1.01 - 2, 2.01 - 3). So the data is skewed, showing that 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.
