Several years ago, 42% of parents who had children in grades K-12 were satisfied with the quality of education the students receive.

Of the 1 comma 075 surveyed, 462 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.
