Several years ago, 33% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,125 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,125 surveyed, 451 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 alternative hypotheses? Ho: P versus H₁: p (Round to two decimal places as needed.)
