Several years ago, 50% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,105 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,105 surveyed, 491 indicated that they were satisfied. Construct a 95% 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 = 0.5 versus H,: p # 0.5 (Round to two decimal places as needed.) Use technology to find the 95% confidence interval. The lower bound is The upper bound is (Round to two decimal places as needed.)
