Hypothesis Test
single population
- p-value
- one-sided
- p-value = P (Ȳ > ȳ| H0 true)
- reject H0
- p-value < α
- fail to reject H0
- p-value ≥ α
- reject H0
- p-value = P (Ȳ > ȳ| H0 true)
- two-sided
- p-value = 2P (Ȳ > ȳ| H0 true)
- reject H0
- p-value < α
- fail to reject H0
- p-value ≥ α
- reject H0
- p-value = 2P (Ȳ > ȳ| H0 true)
- the strength of the evidence for HA
- one-sided
- confidence interval
- one-sided
- L = ȳ - (Zα*σ/√n)
- reject H0
- null value is not inside the CI
- fail to reject H0
- null value is inside the CI
- reject H0
- L = ȳ - (Zα*σ/√n)
- two-sided
- CI = ȳ ± (Z_(α/2)*σ /√n)
- reject H0
- null value is not inside the CI
- fail to reject H0
- null value is inside the CI
- reject H0
- CI = ȳ ± (Z_(α/2)*σ /√n)
- the range of likely values for the effect
- one-sided
- hypothesis testing
- one-sided
- Zs = test statistic Zα = critical value
- reject H0
- Zs > Zα
- fail to reject H0
- Zs ≤ Zα
- reject H0
- Zs = test statistic Zα = critical value
- two-sided
- Zs = test statistic Zα/2 = critical value
- reject H0
- |Zs| > Zα/2
- fail to reject H0
- |Zs| ≤ Zα/2
- reject H0
- Zs = test statistic Zα/2 = critical value
- gives yes/no answer
- one-sided
- p-value
two populations
- p-value
- p-value = 2P (Ȳ1 - Ȳ2 > ȳ1 - ȳ2| H0 true)
- reject H0
- p-value < α
- fail to reject H0
- p-value ≥ α
- reject H0
- p-value = 2P (Ȳ1 - Ȳ2 > ȳ1 - ȳ2| H0 true)
- confidence interval
- (ȳ1 - ȳ2) ± Zα/2 * √{ [ (σ1)^2 / n1] + [(σ2)^2 / n2]}
- reject H0
- 0 is not inside the CI
- fail to reject H0
- 0 is inside the CI
- reject H0
- (ȳ1 - ȳ2) ± Zα/2 * √{ [ (σ1)^2 / n1] + [(σ2)^2 / n2]}
- hypothesis testing
