Several years ago, 45% of parents with children in grades K-12 were satisfied with the quality of education the students receive. A recent poll found that 495 of 1,125 parents with children in grades K-12 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. E Click the icon view the Confidence Interval Critical Value table. What are the null and alternative hypotheses? Ho: p O versus H,: p (Type integers or decimals. Do not round.) Find the 99% confidence interval. The lower bound is The upper bound is (Round to three decimal places as needed.) What is the correct conclusion? O A. 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 B. 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 C. 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 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.
