LaGuardia Community College was part of a grant by the National Science Foundation with the 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 economics applications would improve student attitudes about college algebra. Faculty designed a survey that would score students' attitudes with respect to college algebra on a scale of 1-10. Ten college algebra sections (classes) were selected based on which faculty members responded first to an email request. Out of these 10 sections, 5 instructors agreed to use the economics applications. The other five sections just used the usual curriculum without the economics applications. It was found that the classes who had the economics applications had a mean score of 6.5. Whereas the other group had a mean score of 6.

2. Is this an observational study or an experiment? If this is an experiment state the explanatory variable and the response variable. 3. What is the sample used in the study? 4. Was there random selection? If not, which sampling method was used to create the sample? (convenience, systematic, or stratified) 5. Was there random assignment into groups? 6. Is it reasonable to conclude that the introduction of economics topics into the college algebra curriculum caused student attitudes to improve? 7. Are the results generalizable to the entire population? Why or why not?
