To test Ho: 6 = 2.3 versus H1: 6 > 2.3, a random sample of size n = 24 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be s = 2.6, compute the test statistic. (b) If the researcher decides to test this hypothesis at the a = 0.05 level of significance, use technology to determine the P-value. (c) Will the researcher reject the null hypothesis? (a) The test statistic is x = 29.39 . (Round to two decimal places as needed.) (b) The P-value is 0.168 . (Round to three decimal places as needed.) (c) Since the P-value is greater than the level of significance, the researcher will not reject the null hypothesis Ho: 6 = 2.3.Several years ago, 41% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1, 175 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1, 175 surveyed, 482 indicated that they were satisfied. Construct a 99% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. . . . What are the null and alternative hypotheses? Ho: p = .41 versus H, : p # .41 (Round to two decimal places as needed.) Use technology to find the 99% confidence interval. The lower bound is 0.37 . The upper bound is 0.45 . (Round to two decimal places as needed.)
