Confidence Interval for Difference Between Means

All confideence intervals stay the same:

$$Confidence Interval = Point Estimate\pm ME$$

$$ME=Critical Value * SE of Point Estimate$$

Our point estimate becomes:

$$Point Estimate=\bar{x}_1-\bar{x}_2$$

And our standard error changes slightly:

$$SE_(\bar{x}_1-\bar{x}_2)=\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$$
