Question
In a controlled laboratory environment a random sample of 10 adults and a random sample of 10 children were tested by a psychologist determine the room temperature that each person finds most comfortable. The data are summarized below If the psychologist wished to test the hypothesis that adults prefer warmer room temperatures than children, which set of hypotheses would he use? H_O (mu_1 - mu_2) = 3 vs H_a: (mu_1 - mu_2) notequalto 3 H_O (mu_1 - mu_2) = 0 vs H_a: (mu_1 - mu_2) notequalto 0 H_O (mu_1 - mu_2) = 0 vs H_a: (mu_1 - mu_2) > 0 H_O: (mu_1 - mu_2) = 0 vs H_a: (mu_1 - mu_2)Explanation / Answer
