Bug Description

The results of the Independent sample T-test in equivalence test module for the upper and lower bound seem to be switched. As I had the confidence interval of the results including the lower limit of the equivalence region, yet the results showed significant P-value for the lower bound. While, the confidence interval of the results not including the upper limit of the equivalence region, yet it shows non-significant P-value.

Equivalence region: -2 : +2
The test results CI: -2.45 : +0.92
The upper bound P-value: 0.113
The lower bound P-value: 0.004

Expected Behaviour

Equivalence region: -2 : +2
The test results CI: -2.45 : +0.92
The upper bound P-value: 0.004
The lower bound P-value: 0.113
