Student researchers at Hope College conducted an experiment to determine whether students memorize material better if they are taking notes on paper using handwriting as opposed to taking notes on a computer. They randomly assigned 20 students to the paper-based note-taking group and 20 students to the computer-based note-taking group. They showed all their subjects a 12-minute video about the sun and they were allowed to take notes in the method they were assigned. After the video was over, the notes were collected, and the students were given a 10-question quiz over information about the sun given in the video. Do students tend to memorize better using hand-written notes? (The results data are in the file NoteTaking picture)

Extracted text: (a) Put the data in the Multiple Means applet to create a null distribution and from it calculate a 2SD confidence interval for the difference in mean difference quiz scores between the two types of note-taking groups. Choose best among the following options. 0.000 ± 2(0.550) = (-1.1, 1.1) 1.425 t 2(0.550) (0.325, 2.525) 5.50 ± 2(2.04) = (1.42, 9.58) 6.21 t 2(1.63) = (2.95, 9.47) 6.92 2(1.07) = (4.78, 9.06) eTextbook and Media (b) Explain what your interval from part (a) means in context. Taking notes on paper will result in quiz scores that are -1.1 to * poin in the long run. lower higher eTextbook and Media lower, on average higher, on average (c) Based on your interval, is there strong evidence of a difference in the mean quiz scores between the two types of note-taking groups? Yes, there is strong evidence of a mean difference in quiz scores between the two types of note-taking groups because 0 is included in the interval. O Yes, there is strong evidence of a mean difference in quiz scores between the two types of note-taking groups because O is not included in the interval. No, there is not strong evidence of a mean difference in quiz scores between the two types of note-taking groups because O is included in the interval. No, there is not strong evidence of a mean difference in quiz scores between the two types of note-taking groups because 0 is not included in the interval.
