Several years ago, 49% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,005 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive of the 1,005 surveyed, 473 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 altemative hypotheses? HP versus H, p o (Round to two decimal places as needed) Use technology to find the 90% confidence interval The lower bound is The upper bound is (Round to two decimal places as needed.) What is the correct conclusion? A. Since the interval contains the proportion stated in the null hypothesis, there is sufficient evidence that parents' attitudes toward the quality of education have changed B. Since the interval does not contain the proportion stated in the null hypothesis, there is insufficient evidence that parents' attitudes to C. Since the interval does not contain the proportion stated in the hypothesis, there is sufficient evidence that parents attitudes toward the quality of education have changed D.Since the interval contains the proportion stated in the hypothesis, there is insufficient evidence that parents des toward the quality of education have changed
