Problem 2LaGuardia Community College was part of a grant by the National Science Foundation withthe goal of improving the College Algebra curriculum but introducing economics applications.Part of the grant required conducting a study to determine if the addition of economicsapplications would improve student attitudes about college algebra. Faculty designed asurvey that would score students' attitudes with respect to college algebra on a scale of1-10. Ten college algebra sections (classes) were selected based on which faculty membersresponded first to an email request. Out of these 10 sections, 5 instructors agreed to use theeconomics applications. The other five sections just used the usual curriculum without theeconomics applications. It was found that the classes who had the economics applicationshad a mean score of 6.5. Whereas the other group had a mean score of 6.1. What is the research question being asked?

Wegman’s (a food market chain) has developed a new store-brand brownie mix. Before they start selling the mix they want to compare how well people like their brownies to brownies made from a popular national brand mix. In order to see if there was any difference in consumer opinion, Wegman’s asked 124 shoppers to participate in a taste test. Each was given a brownie to try. Subjects were not told which kind of brownie they got—that was determined randomly. 58% of the 62 shoppers who tasted a Wegman’s brownie said liked it well enough to buy the mix, compared to 66% of the others who said they would be willing to buy the national brand. Does this result indicate that consumer interest in the Wegman’s mix is lower than for the national brand?
