Suppose I measure some treatment response on a set of 10 mice from strain A, and receive the following data:
| 84 | 106 | 99 | 101 | 100 |
| 99 | 127 | 105 | 101 | 108 |
Note that n=10, the sample mean is 103 and the sample SD is 10.67.
Suppose I measure the same sort of treatment response on a set of 5 mice from strain B, and receive the following data:
| 56 | 62 | 67 | 81 | 69 |
Note that m=5, the sample mean is 67 and the sample SD is 9.30.
Calculate a 95% confidence interval for the difference in the average treatment responses of strains A and B.
