Several years ago, 40% 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.

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? Hop versus H, : P VO (Round to two decimal places as needed.) Use technology to find the 99% confidence interval. The lower bound is The upper bound is Round to two decimal places as needed.) What is the correct conclusion? O A. Since the interval contains the proportion stated in the null hypothesis, there is insufficient evidence that parents' attitudes toward the quality of education have changed. O B. Since the interval does not contain the proportion stated in the null hypothesis, there is insufficient evidence that parents' attitudes toward the quality of education have changed. O C. Since the interval does not contain the proportion stated in the null hypothesis, there is sufficient evidence that parents' attitudes toward the quality of education have changed. O D. 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
