**Two sample T hypothesis test final lab**

### Two sample T hypothesis test:

μ

_{1}: Mean of Aud-Before

μ

_{2}: Mean of Aud-After

μ

_{1}- μ

_{2}: Difference between two means

H

_{0}: μ

_{1}- μ

_{2}= 0

H

_{A}: μ

_{1}- μ

_{2}≠ 0

(without pooled variances)

**Hypothesis test results:**

Difference | Sample Diff. | Std. Err. | DF | T-Stat | P-value |
---|---|---|---|---|---|

μ_{1} - μ_{2} | 91.872529 | 15.41853 | 194.24251 | 5.958579 | <0.0001 |
