practice analyzing data sets. which of the distributions is left - skewed?

Explanation:

Step1: Recall left - skewed distribution

In a left - skewed distribution, the tail of the distribution extends to the left. That is, there are a few relatively small values that pull the tail in the left direction.

Step2: Examine each histogram

For the first histogram, the tail extends to the left as the bars decrease in height towards the left side. For the second histogram, it has a gap in the middle and is not clearly left - skewed. For the third histogram, the tail extends to the right (right - skewed). For the fourth histogram, it is approximately symmetric.

Answer:

The first distribution (from the left) is left - skewed.
