Hypothesis Testing Flashcards
Hypothesis definition
A statement made about the value of a population parameter
Hypothesis testing
Uses a sample/experiment to determine whether to reject or accept the hypothesis
Population parameter definition
The probability in a binomial distribution
Null hypothesis (H0)
What we assume to be correct
Alternative hypothesis (H1)
Tells us about the population parameter if our assumption is shown to be correct
Test statistic definition
Result of experiment/statistic calculated form the sample+consider its chance of actually happening
Significance level definition
Threshold we reject H0
If test statistic<SL=reject H0/accept H1
One tailed test
Inequality sign is same as H1for the binomial distribution
If u can’t tell, calculate expected outcome (nxp)
Two tailed test
p≠
Divide sig lvl by 2
Critical region definition
Range of values of the test statistic that would lead to rejecting H0
Critical value definition
Value(s) on the boundary of critical region
Actual sig lvl definition
Actual prob of being in critical region (add prob of critical values)
