SAT scores: Scores on the math SAT are normally distributed. A sample of 21 SAT scores had standard deviation s=85. Someone says that the scoring system for the SAT is designed so that the population standard deviation will be o =61. Do these data provide sufficient evidence to contradict this claim? Use the a=0.10 level of significance. Part 1 of 5 State the null and alternate hypotheses. H :o = 61 X 5 61 This hypothesis test is a two-tailed test. Part 2 of 5 Find the critical values. Round the answers to three decimal places. The critical values are 9.591 and 34.17 X
