Several years ago, 35% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,195 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,195 surveyed, 483 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 H,: p (Round to two decimal places as needed.)
