a. a person's height and the person's grade on the math test
there is no way that is correct
Apologies for the incorrect response. The correct pair of variables that would likely be represented by a scatterplot with a negative correlation is:

b. the depth of the water in a pond and the amount of rainfall
b is a positive correlation
Apologies for the error once again. You are correct, the depth of the water in a pond and the amount of rainfall would actually be expected to have a positive correlation, as an increase in rainfall would typically result in an increase in pond water depth.

The correct answer is:

d. the number of concert tickets purchased and the number of concert tickets still available for purchase. In this scenario, as the number of concert tickets purchased increases, the number of concert tickets still available for purchase would decrease, showing a negative correlation.
