Afamily considering adopting a dog is considering Labradors golden retrievers and pugs. They would like to know if these breeds shed different amounts of fur. They brush a random sample of 15 dogs of each type and measure the mass of fur left on the brush after each. the appropriate hypothesis test is:

A) t- test for the population portion

B) z-test for the population proportion

C) t- test for the population mean

D) z-test for the population mean

E) ANOVA test for the means

- please explain in detail why each one isn't the answer and why the correct one is correct

Answer #1

The answer is:

This is because we are measuring the average amount of fur left on the brush. We have been provided with no population variance, so we will be using the t-test for the difference in the population means between two independent samples.

{Assumed when it said t-test for the population mean, that meant that the t-test for the difference in the population means between two independent samples.}
