The correct answer is C. Graph showing positively skewed distribution with a peak to the left of the curve and tail to the right.
Explanation:
The purpose of a graph is to show visually numerical data, including how this changes over time. In the situation presented, the test scores fell or decreased after the hurricane.
In this context, it is expected before the hurricane the test scores were high, which should be represented as a peak in the graph as the rate for test scores was high.
Moreover, once the hurricane occurs the peak should decrease, this is represented as a tail in the graph as the scores of students fell or decrease. According to this, the graph that best represents this situation is one "graph showing positively skewed distribution with a peak to the left of the curve and tail to the right".
