Let x represent the number of bullfrogs in the population.
We have been given that in a study of the population density of bullfrogs, 25 are captured and marked in the first sampling. Five days later, 30 frogs are captured, 10 of which have marks.
We will use proportion to solve our given problem as:
Therefore, the estimated number of bullfrogs in the population would be 75.

Class limits are the smallest and the largest data value that can go into a class.
Class marks are the midpoints of the classes. They are obtained by averaging the limits.
Cutpoints are<span> specified values used to sort continuous variables into discrete categories.

For qualitative data, </span>c<span>utpoints and midpoints make sense, but class limits and marks do not, since qualitative data cannot be grouped using Limit grouping.
