The authors of the paper ?Reading Subtitles and Taking Enotes While Learning Scientific Materials in a Multimedia Environment? (Educational Technology and Society [2016): 47?58) were interested in determining if including subtitles and providing opportunities to take electronic notes while listening to online materials would enhance learning for students whose first language is not English. Students were randomly assigned to one of four groups. In the first group, subtitles were included in the online materials that the students were asked to study, but the ability to take electronic notes was not provided. For the second group, no subtitles were provided, but students were able to take electronic notes. For the third group, both subtitles and the ability to take electronic notes were available. Students in the fourth group did not have access to either subtitles or the ability to take electronic notes. After studying the online materials, all students took a 14-question test on the material studied. The Minitab output based on data consistent with summary quantities in the paper is shown below. Is there evidence to conclude that the mean test score is not the same for the four different treatments? Use the given computer output to test the appropriate hypotheses with a significance level of 0.05.
