Formulae for Hypothesis Testing
- Large sample statistical test
θ may equal µ p, (µ1 – µ2), or (p1 – p2)
Ho : θ = θo
Ha : θ > θo or Ha : θ < θo
Ha : θ ≠ θo
Reject Ho if Z > Zα or if Z < – Zα
Reject Ho if Z > Za/2 or if Z < –Za/2
- Small-sample test for a population mean
Ho : µ = µo
Ha : µ > µo or µ < µo
Reject Ho if t > tα or if t < –tα
Reject Ho if t > tα/2 or if t < –tα/2
- Small-sample ...
