Question

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. is paris correct in her predictions? check all the apply. yes, her samples represent the population. no, paris should have used only the results of the first sample. no, paris should have used only the results of the second sample. no, the two samples do not have similar values, so more samples are needed. no, the samples are not representative of the population.

Explanation:

For accurate predictions about a population, samples should be representative. Here, the two samples have very different frequencies for trout and bass (e.g., 12 vs 1 for trout and 13 vs 23 for bass). This indicates that the samples may not be representative of the population in the pond. Using only one sample would also be inaccurate as a single - sample may not capture the true distribution. More samples are needed when sample values vary greatly.

Answer:

No, the two samples do not have similar values, so more samples are needed.
No, the samples are not representative of the population.
