Several years ago, 38% of parents with children in grades K-12 were satisfied with the quality of education the students receive. A recent poll found that 454 of 1,205 parents with children in grades K-12 were satisfied with the quality of education the students receive. Construct a 90% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. E Click the icon to view the Confidence Interval Critical Value table What are the null and alternative hypotheses? Ho:p = 38 versus H,: p # 38 (Type integers or decimals. Do not round.) Find the 90% confidence interval. The lower bound is The upper bound is (Round to three decimal places as needed.)
