Question

In August 2002, 47% of parents who had children in grades K–12 were satisfied with the quality of education the students receive. In September 2010, the Gallup organization conducted a poll of 1013 parents who have children in grades K–12 and asked if they were satisfied with the quality of education the students receive. Of the 1013 surveyed, 437 indicated that they were satisfied. Construct a 95% confidence interval to assess whether this represents evidence that parents’ attitudes toward the quality of education in the United States has changed since August 2002.
