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 1,115 parents who have children in grades were satisfied with the quality of education the students receive. Of the 1,115 surveyed, 488 indicated that they were satisfied.

Question
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 1,115 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,115 surveyed, 488 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 ▼ versus H₁: p (Type integers or decimals rounded to two decimal places as needed.) Use technology to find the 95% confidence interval. We are 95% confident the proportion of parents who had children in grades K-12 that were satisfied with the quality of education the students receive is between and (Type integers or decimals rounded to two decimal places as needed.) What is the correct conclusion? OA. 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. OB. 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. OC. 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. OD. 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 COLO CO 8 F10 1000 F11 F12 Ys Insert PrtSc Delete @4x ► 11 Next 7:57 PM 12/4/2022 .
