Question

You decide to determine, once and for all, which chocolate brownies are best-- yours or your sister-in-law's Yolanda-- by devising a hypothesis test. She is a superb baker and she mocks your baking as inferior. Undaunted, you decide to randomly select 100 names from the NYC phone book. You contact each selected individual and they agree to participate in your study. 50 are sent your brownies and the other 50 fifty are sent Yolanda's. Each group rates the brownies on a 10 point ordinal scale--10 implies exquisite and 1 implies inedible.

True or False: This test is performed on independent samples.

Explanation / Answer

Here each individual are independent from each other and each individual are selected randomly in one of the two groups.

That is here we have two independent samples : One who sent your brownies and second who sent Yolanda's brownies

So answer is "True"
