7.6 Welch (Unpooled Variance) t Tests and Confidence Intervals: An Example

I work through an example of a Welch (unpooled variance) t test and confidence interval (in the setting of inference for two means).

The antivenom/swelling data is found in:

Offerman et al. (2009). Subcutaneous crotaline Fab antivenom for the treatment of rattlesnake envenomation in a porcine model. Clinical Toxicology, 47: 61-68.
