SAT scores: Scores on the math SAT are normally distributed. A sample of 29 SAT scores had standard deviation s = 90. Someone says that the scoring system for the SAT is designed so that the population standard deviation will be at most o= 84. Do these data provide sufficient evidence to contradict this claim? Use the a = 0.05 level of significance. Part: 0 / 5 Part 1 of 5 State the null and alternate hypotheses. Ho: (Choose one) X H : (Choose one) This hypothesis test is a (Choose one) test. Part: 1 / 5Find the critical value. Round the answer to three decimal places. For a= 0.05, the critical value is C]. [j Compute the test statistic. Round the answer to three decimal places. Esp Determine whether to reject H0. (Choose one) V the null hypothesis H0. State a conclusion. There (choose one) V enough evidence to contradict the claim that the population standard deviation is at most 0'= 84
