What happens to the power of a test as the sample size increases?a.The power decreasesb.The power increasesc.The power remains the samed.The power becomes undefinedClear my choice

By increasing the sample size, what change will be observed in statistical power?1 pointThe power will decrease.A change in power cannot be predicted from sample size.The power will not change.The power will increase.

Recall that the power of a test is the probability that we reject H_0 when H_0 is false. Which of the following are true? Select one or more answers.Group of answer choicesIf sample size increases then power increases.If H_0 is very likely to be true then the power is higher when compared to when H_0 is very likely to be false.If α increases then power increases.If the effect size increases then power increases.
