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

![### Educational Content on Confidence Intervals in Multiple Means Analysis
#### (a) Null Distribution and Confidence Interval Selection
To find the best confidence interval for the difference in mean quiz scores between two types of note-taking groups, we used the Multiple Means applet. The objective was to calculate a 2SD (two standard deviations) confidence interval and identify the most appropriate option from the following:
- **0.000 ± 2(0.550) = (-1.1, 1.1)**
- 1.425 ± 2(0.550) = (0.325, 2.525)
- **5.50 ± 2(2.04) = (1.42, 9.58)**
- 6.21 ± 2(1.63) = (2.95, 9.47)
- 6.92 ± 2(1.07) = (4.78, 9.06)
#### (b) Interpretation of Confidence Interval in Context
The chosen interval from part (a) suggests that taking notes on paper will result in quiz scores that are **-1.1** to [selected option: lower/higher/lower, on average/higher, on average] in the long run.
#### (c) Evidence of a Mean Difference
Based on the interval selected, evaluate the evidence of a difference in the mean quiz scores between the two types of note-taking groups:
- Option 1: Yes, there is strong evidence of a mean difference in quiz scores between the two types because 0 is included in the interval.
- Option 2: Yes, there is strong evidence of a mean difference in quiz scores between the two types because 0 is not included in the interval.
- Option 3: No, there is not strong evidence of a mean difference in quiz scores between the two types because 0 is included in the interval.
- Option 4: No, there is not strong evidence of a mean difference in quiz scores between the two types because 0 is not included in the interval.
In educational contexts, understanding these intervals helps in interpreting the statistical significance and practical relevance of different teaching methods.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F51e5bd93-2fba-48ff-bc45-ddb57f441493%2Ff3707324-2d21-41e9-a8b3-1a91cee61940%2Fwzsjvde_processed.jpeg&w=3840&q=75)

Transcribed Image Text:**Data Analysis of Paper vs. Computer Methods**
This dataset provides scores based on two different methods: "Paper" and "Computer." The scores reflect a certain measure of performance or results obtained through each method.
**Paper Method Scores:**
- 5.5, 5.5, 7, 6.5, 7.5, 5, 8.5, 6, 7.5, 8, 6.5, 7.5, 7, 9, 7, 6, 8.5, 6.5, 7, 6.5
**Computer Method Scores:**
- 8, 7.5, 3.5, 3.5, 8.5, 5, 1, 5.5, 4, 7.5, 8, 7, 4, 5, 4.5, 5, 5, 7, 3, 7.5
**Analysis:**
- The scores for the "Paper" method tend to be higher overall, with a few scores reaching up to 9.
- The "Computer" method scores range widely but include several lower scores, such as 1 and 3.5, indicating more variability.
This data can be used to analyze the effectiveness and consistency of each method in achieving high scores.
