Several years​ ago,39​% of parents who had children in grades​ K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,085 parents who have children in grades​ K-12 if they were satisfied with the quality of education the students receive. Of the 1,085 surveyed, 498 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?

H0: P= 0.39 versus H1: P≠ 0.39

(Round to two decimal places as​ needed.)
