Question

residents in a city are charged for water usage every three months. the water bill is computed from a common fee, along with the amount of water the customers use. the last water bills for 40 neighborhood residents are displayed in the histogram below. which of these correctly describes the shape of the distribution of water bills? uniform skewed left skewed right roughly symmetric

Explanation:

• A uniform distribution has bars of approximately equal height. This histogram does not have that.
• A left - skewed distribution has a longer tail on the left. This histogram does not have a longer tail on the left.
• A right - skewed distribution has a longer tail on the right. This histogram does not have a longer tail on the right.
• A roughly symmetric distribution has a shape where the left and right sides are approximately mirror images. Looking at the histogram, the left and right sides around the center (around 200 - 225 range) are somewhat balanced in terms of the spread of frequencies.

Answer:

roughly symmetric
