Classify the conclusion of the hypothesis test as a Type I error, a Type Il error, or a correct decision. In 1993, the average math SAT score for students at one school was 471. Five years later, a teacher wants to perform a hypothesis test to determine whether the average math SAT H,:µ=D471 score of students at the school has changed from the 1993 mean of 471. The hypotheses are: H, :µ ± 471 Suppose that the results of the sampling lead to rejection of the null hypothesis. Classify that conclusion as a Type I error, a Type Il error, or a correct decision, if in fact the average math SAT score of students at the school has changed from the 1993 mean of 471.

4. Dr. Phil wanted to know if mothers give more hugs to their children than fathers do. He used 8 married couples so that each mother and father would be matched on the number of children for his sample. Dr. Phil then asked each parent to report the number of hugs that they gave their children over the course of 2 weeks. Assume the parametric assumptions were NOT violated. Conduct an appropriate statistical test for him using alpha .05 and the eight steps of hypothesis testing.
