An education company representative, speaking on a local radio station, has advocated that middle school students download a particular app on their phone. the individual cited a study of 1,000 randomly selected middle school seventh- and eighth-grade students that reported that students who downloaded the app on their phones, on average, scored 30 points higher on the algebra i end-of-course exam than those who did not download the app. which of the following statements is correct?
there seems to be a relationship between the app and obtaining a higher score on the algebra i exam.
because downloading the app seems to improve standardized test scores for middle school students, the app should be effective for high school students.
downloading the app will cause a student to score higher on an ap statistics exam.
the study was an experiment rather than an observational study.
the sample size of the study was too low to determine a result.
