1p(A) = p(A)+p(B)
- AThe probability of getting B is the sum of A and B
- BThe probability of getting A is the sum of A and B
2What is the equation for the probability of and event happening and not happening?
- Ap(A)+p(B) = 1
- Bp(A) + p(no A) = 1
3If 2 events are independant the probability of event A and event B are the [blank_start]probabilities of event A and B[blank_end]
- Aprobabilities of event A and B
- Bprobability of A
- CProbability of B
4If level of significance (alpha) is below 5% then we [blank_start]reject the null hypothesis[blank_end]
- Areject the null hypothesis
- Baccept the null hypothesis
5A type 1 error is where there is a [blank_start]5%[blank_end] chance the null hypothesis is [blank_start]rejected when it is true.[blank_end]
- A5%
- B10%
- Caccepted when false.
- Drejected when it is true.
6Bonferroni correction is for type 1 errors
- ARichtig
- BFalsch
7How do you apply Bonferroni correction?
- ADivide P value by 2
- BDivide p value by number of corrections
8A type 2 error is the [blank_start]acceptance of a incorrect[blank_end] null hypothesis
- Arejection of the
- Bacceptance of a incorrect
