Question

monitors the water quality of the lakes in cottonwood county. he takes water and then tests their ph levels. this histogram shows the distribution of ph leve in the lakes he monitored last month. lake water samples complete the sentences. the distribution of ph levels is best described as. so, the mean an appropriate measure of center.

Explanation:

Step1: Analyze the histogram shape

Looking at the histogram, we can see that the distribution is symmetric. In a symmetric distribution, the left - hand side of the histogram is a mirror image of the right - hand side.

Step2: Recall the property of mean in symmetric distribution

For a symmetric distribution, the mean is an appropriate measure of center. This is because the values are evenly distributed around the center, and the mean (which is calculated as \(\frac{\sum_{i = 1}^{n}x_{i}}{n}\)) will accurately represent the central tendency.

Answer:

The distribution of pH levels is best described as symmetric. So, the mean is an appropriate measure of center.
