The correct answer is: 4. skewed; is.
Explanation: If the distribution of pH levels is skewed, it means that it does not follow a symmetrical pattern and may have a long tail on one side. In cases of skewed distributions, the mean can still be an appropriate measure of center, but it may not fully represent the typical pH level since it can be influenced by extreme values. In this context, it suggests that the mean is relevant despite the skewness.
