Question
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?
Question 11 options:
H0: (1 - 2) = 0 vs. H0: (1 - 2) < 0
H0: (1 - 2) = 3 vs. H0: (1 - 2) 0
H0: (1 - 2) = 0 vs. H0: (1 - 2) = 0
H0: (1 - 2) = 0 vs. H0: (1 - 2) > 0
Explanation / Answer
as our claim is that temperature preference of children is higher then adults; therefore hypothesis are:
H0: (1 - 2) = 0 vs. H0: (1 - 2) < 0
