Question 1

In a controlled laboratory environment, a random sample of 10 adults and a random sample of 10 children were tested by a psychologist to determine the room temperature that each person finds most comfortable. The data are summarized below:




If the psychologist wished to test the hypothesis that children prefer warmer room temperatures than adults, which set of hypotheses would he use?
H0: (μ1 - μ2) = 0 vs. H0: (μ1 - μ2) = 0
H0: (μ1 - μ2) = 0 vs. H0: (μ1 - μ2) > 0
H0: (μ1 - μ2) = 3 vs. H0: (μ1 - μ2) ≠ 0
H0: (μ1 - μ2) = 0 vs. H0: (μ1 - μ2) < 0

Question 2

Consider the following set of salary data:



To determine if women have a higher mean salary than men, we would test:
H0: μ1 - μ2 = 0 vs. Ha: μ1 - μ2 = 0
H0: μ1 - μ2 = 0 vs. Ha: μ1 - μ2 ≠ 0
H0: μ1 - μ2 = 0 vs. Ha: μ1 - μ2 < 0
H0: μ1 - μ2 = 0 vs. Ha: μ1 - μ2 > 0
