A study will be conducted to investigate whether there is a difference in the mean weights between two populations of raccoons. Random samples of raccoons will be selected from each population, and the mean sample weight will be calculated for each sample.

Which of the following is the appropriate test for the study?

a) A one-sample z-test for a population proportion.

b) A one-sample t-test for a population mean.

c) A two-sample t-test for a difference between sample means.

d) A two-sample t-test for a difference between population means.

e) A two-sample z-test for a difference between population proportions.

In this case, the answer would be option d) given in the answer choices or options or A two-sample t-test for a difference between population means.

Step-by-step explanation:

In Statistics, a two sample test is generally used to examine or compare two different population means with the main objective to verify whether the population means are equal or otherwise. The two sample t-test basically involves the hypothesis testing to determine or verify the equality between two concerned population means. In this case, the two different populations of raccoons are given and the equality of the mean sample weights of the two distinct populations can be determined or evaluated by employing the hypothesis testing method under a two sample t test for measuring difference in two population means.
