Question:
(Create a scatterplot and describe what you learn from it. Then complete all six steps of hypothesis testing.)
Identifying individuals with a high risk of Alzheimer?s disease usually involves a long series of cognitive tests. However, researchers have developed a 7-Minute Screen, which is a quick and easy way to accomplish the same goal. The question is whether the 7-Minute Screen is as effective as the complete series of tests. To address this question, Ijuin et al. (2008) administered both tests to a group of patients and compared the results. The following data represent results similar to those obtained in the study.
| 7-Minute Screen | Cognitive Series |
| 3 | 11 |
| 8 | 19 |
| 10 | 22 |
| 8 | 20 |
| 4 | 14 |
| 7 | 13 |
| 4 | 9 |
| 5 | 20 |
| 14 | 25 |
Hypothesis
Hypothesis testing is the best way to estimate differences between two data, In hypothesis testing, we find test statistics value, critical value and p-value then we come to the conclusion point and conclude that which hypothesis reject or accept.
