A lоcаl cоmpаny shоwed the following two stаtements to a random sample of 500 students in California. Language Arts Statement:  Mastery of language arts standards should be given priority over mastery of mathematics standards. Mathematics Statement:  Mastery of mathematics standards should be given priority over the mastery of language arts standards. The order in which the statements were shown was randomly selected for each student in the sample.  After reading the statements, each student was asked to choose the statement that was most consistent with his or her opinion.  The results are shown in the table. Language Arts Statement Mathematics Statement No Preference Percent of sample 56% 35% 9%   a.  Construct and interpret a 95% confidence interval for the proportion of all adults in the United States who would have chosen the Mathematics statement.   b.  Interpret the "95% confidence level" in this context.
