Determine whether the samples are independent or dependent.To test the effectiveness of a drug, cholesterol levels are measured in 150 men and 150 women after the treatment.Choose the correct answer below.A. The samples are independent because there is a natural pairing between the two samples.B. The samples are dependent because there is a natural pairing between the two samples.C. The samples are independent because there is not a natural pairing between the two samples.D. The samples are dependent because there is not a natural pairing between the two samples.

Matched paired design: In this design two samples are related to each other and a natural pairing…

Answered: Determine whether the samples are…

A seafood festival organizer is interested in whether there is a relationship between the number of ingredients in the clam chowders that are entered in the festival’s clam chowder contest and the ratings given to the chowders by the judges. The organizer requires each of the twelve restaurants in the competition to list all of its chowder's ingredients and requires each judge who tastes the clam chowders to rate each chowder from one through ten on a note card. The organizer then randomly selects twenty-five note cards. Assuming that all conditions for inference are met, which of the following significance tests should be used to investigate whether having more ingredients in the chowders is associated with a reduction in the ratings given to the chowders by the judges? A)A chi-square test of independence B)A two-sample t-test for a difference between means C)A two-sample z-test for a difference between proportions D)A linear regression t -test for slope…
