Which of the following is an accurate definition for the power of a statistical test?​Group of answer choices​The probability of rejecting a false null hypothesis​The probability of supporting a false null hypothesis​The probability of rejecting a true null hypothesis​The probability of supporting true null hypothesis

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.

There is a direct relationship between the power of a test and the probability of a Type II error.Group of answer choicesTrueFalse

What is statistical power?Review LaterThe probability of correctly rejecting the null hypothesis when the alternative hypothesis is true.The probability of committing a Type I error (false positive), which is rejecting the null hypothesis when it is true.The probability of committing a Type II error (false negative), which is failing to reject the null hypothesis when the alternative hypothesis is true.None of the above
