H0: λ = λ0 | The population rate of occurrence (λ) equals the hypothesized rate of occurrence (λ0). |
H1: λ ≠ λ0 | The population rate of occurrence (λ) differs from the hypothesized rate of occurrence (λ0). |
H1: λ > λ0 | The population rate of occurrence (λ) is greater than the hypothesized rate of occurrence (λ0). |
H1: λ < λ0 | The population rate of occurrence (λ) is less than the hypothesized rate of occurrence (λ0). |
