Paris used a simulation to take two random samples of fish in a pond. Her sample size was 30, and the table shows the frequency of each fish in the sample. Paris used the two samples to predict that the average number of trout will be 6, the average number of catfish will be 5, and the average number of bass will be 18.

Fish type Frequency sample 1 Frequency sample 2

Book trout 12 1

Catfish 5 6

Bass 13 23

A. Yes, her samples represent the population.

B. No, Paris should have used only the results of the first sample.

C. No, Paris should have used only the results of the second sample.

D. No, the two samples do not have similar values, so more samples are needed.

E. No, the samples are not representative of the population.
