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. H_a: μ₁ - μ₂ = 0
◦ H₀: μ₁ - μ₂ = 0 vs. H_a: μ₁ - μ₂ ≠ 0
◦ H₀: μ₁ - μ₂ = 0 vs. H_a: μ₁ - μ₂ < 0
◦ H₀: μ₁ - μ₂ = 0 vs. H_a: μ₁ - μ₂ > 0
