Question

Several years ago, 38% 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, 464 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. The lower bound is? The upper bound is?
