- 11 Null and alternative hypothesisH0: p= _ H1: p< _
- 22 Tailed and signifcanceOne tailed/ two tailed
_% significance level - 33 DistrubutionBinomial X~B(n,p)
Poisson X~Po(y) - 44 ApproximationPoisson approximation for binomial:
np< 10 np= λ
Normal approximation for binomial:
μ= np> 10 o^2= np(1-p)>10
Normal approximation for poisson:
μ= λ o^2= λ - 55 Probability as bad or worseP(X<= _)=
Do continuity correction if using normal approximation - 66 Compare with significance level____ > 0.05
we do reject
____ < 0.05
we do not reject - 77 Conclusion in contextThere is/ is no significant evidence to support claim
- 8Define: Critical regionThe set of values of a test statistic for which the null hypothesis is rejected with a hypothesis test
- 9Define: Null hypothesisOriginal statistic that is being tested
- 10Define: Hypothesis testingA population parameter proposed by the null hypothesis compared with an alternative hypothesis
