Question

To compare two elementary schools regarding teaching of reading skills, 12 sets of identical twins were used. In each case, one child was selected at random and sent to school A, and his or her twin was sent to school B. Near the end of fifth grade, an achievement test was given to each child. The results follow.

Twin Pair	1	2	3	4	5	6
School A	177	152	118	91	124	111
School B	86	137	117	114	116	88

Twin Pair	7	8	9	10	11	12
School A	84	113	116	148	121	83
School B	93	79	92	136	143	109

Use a 0.05 level of significance to test the hypothesis that the two schools have the same effectiveness in teaching reading skills against the alternate hypothesis that the schools are not equally effective.

(a) What is the level of significance?

(b) Compute the sample test statistic. (Round your answer to two decimal places.)
