A recent poll asked 1,145 parents who have children in grades​ K-12 if they were satisfied with the quality of education the students receive. Of the 1,145 ​surveyed, 461 indicated that they were satisfied. Construct a 90​% confidence interval to assess whether this represents evidence that​ parents’ attitudes toward the quality of education have changed.
