5. Possible outcomes of a hypothesis test The following table depicts the four possible outcomes of a hypothesis test: The researcher makes a correct decision [either by correctly rejecting the null hypothesis (H₀) or correctly not rejecting the null hypothesis], makes a Type I error, or makes a Type II error. In each of the following boxes, select the description that matches the outcome. Decision Truth H₀ False H₀ True Reject H₀ Outcome A Outcome B Do not reject H₀ Outcome C Outcome D The probability of a Type I error is , and the probability of a Type II error is .

7. You have seen this question before. Human volunteers were asked to try five types of meat products. One of these was dog food; the others were various types of pâté. The volunteers were asked which of the five was their favorite. Two out of 18 volunteers chose the dog food. Is there evidence that people prefer human food over dog food? Show all four steps of hypothesis testing.
