Answer:
D. A discrete data set because there are a finite number of possible values
Explanation:
If in a test of a method of gender selection, 725 couples used the XSORT method and 368 of them had baby girls. Therefore, this is a discrete data set because there are a finite number of possible values.
A discrete data is a data set in which the number of possible values are either finite or countable.
For continuous data, there are infinitely many possible values in the data set and those values are uncountable, meaning they cannot be counted.
In this scenario, 725 couples used the XSORT method and 368 of them had baby girls. Therefore, this is a discrete data because the values (725 and 368) are finite and can be counted.
