SAT scores: Scores on the math SAT are normally distributed. A sample of 21 SAT scores had standard deviation s = 88. Someone says that the scoring system for the SAT is designed so that the population standard deviation will be at most o - 69. Do these data provide sufficient evidence to contradict this claim? Use the a = 0.01 level of significance. Part: 0 / 5 Part 1 of 5 State the null and alternate hypotheses. H:o 69 X 69 This hypothesis test is a two-tailed test. Part: 1 / 5 Part 2 of 5 Find the critical value. Round the answer to three decimal places. For a = 0.01, the critical value is X
