Imagine, you are given the following dataset that describes the number of chemotherapy cycles and the corresponding total dose (mg) that 10 patients in a cancer study received.
Task:
â–ªPlease calculate the average dose per cycle and derive the 95% confidence interval for the mean estimate. What assumptions are you making?
Please assess the linear association between the number of cycles and the total dose. Interpret the results.
| patient ID | number of cycles of treatment | totdal dose (mg) |
| 13 | 154.4 | |
| 17 | 151.4 | |
| 12 | 102.8 | |
| 13 | 146.2 | |
| 16 | 160.6 | |
| 5 | 40.4 | |
| 15 | 147.4 | |
| 12 | 112.0 | |
