1. Prepare a paper helicopter as follow: Cut Fold 2.5 Unit in cm Figure 1: Paper helicopter design (dimension in cm) 2. Assign I group member to release the helicopter, and another one as timekeeper 3. Drop the paper helicopter from 8 feet height 4. Record the flying time 5. Repeat Step 3 and 4 for ten times 6. Conduct hypothesis testing to prove that the average flying time is 2.55 seconds. Part 2 (Two-sample t-test) 1. Now, switch the helicopter releaser and timekeeper 2. Drop the paper helicopter from 8 feet height 3. Record the flying time 4. Repeat Step 2 and 3 for ten times 5. Conduct hypothesis testing to compare the average of flying time from Part 1 and Part 2 Part 3 (2 sample paired t-test, and ANOVA) 1. Add a paper clip and/or sellotape to the helicopter body 2. Remain the helicopter releaser and timekeeper as in Part 2 3. Drop the paper helicopter from 8 feet height 4. Record the flying time 5. Repeat Step 3 and 4 for ten times 6. Conduct hypothesis testing to compare the average of flying time from Part 2 and Part 3 7. Conduct hypothesis testing to compare the average of flying time from Part 1, Part 2 and Part 3 Assignment submission must be submitted individually and consist of the following elements: 1. Introduction, background and objective (1 page) 2. Methodology - Explain, include the picture of your paper helicopter, and your group members doing the test (2 pages) 3. Calculation (2 pages) 4. Data and analysis for each of parts (4 pages) 5. Summary, conclusion and practical meaning for each parts (1 page) SUBMISSION DUE: WEEK 7 (30 Nov 2023) 1.
