2.what is the probability that a test correctly rejects a false null hypothesis​ called?

Power is the probability of rejecting the null hypothesis when, in fact, it is false. Power is the probability of making a correct decision (to reject the null hypothesis) when the null hypothesis is false. Power is the probability that a test of significance will pick up on an effect that is present.

What Is Power?

3.what is the probability that a test correctly rejects a false null hypothesis​ called?

Question 4 Power is the probability that a hypothesis test will correctly reject a false null hypothesis. the probability that a hypothesis test will correctly reject a true null hypothesis. O the probability of rejecting a null hypothesis when in fact it is true. the probability of failing to reject a null hypothesis when in fact is is false.

4.what is the probability that a test correctly rejects a false null hypothesis​ called?

The smaller the significance level, the stronger the evidence that is required to reject the null hypothesis. See FAQ 2.3.1 for more details. If I get a p-value ≤ 0.05 then my results are always significant, right? FAQ 2.3.1 The probability of rejecting a false null hypothesis is called the power of the test.

5.what is the probability that a test correctly rejects a false null hypothesis​ called?

Power of a one sided test is greater than the power of the associated two sided test Power goes up as gets further away from Power goes up as goes up Power doesn’t need , and , instead only · · · · · · · The quantity is called the effect size, the difference in the means in standard deviation units.

6.what is the probability that a test correctly rejects a false null hypothesis​ called?

so, that’s why when p<0.01 we reject the null hypothesis, because it's too rare (p0.05, i can understand that for most cases we cannot accept the null, for example, if p=0.5, it means that the probability to get a statistic from the distribution is 0.5, which is totally random.

7.what is the probability that a test correctly rejects a false null hypothesis​ called?

Power: If the alternative hypothesis is true (using the definition of the alternative hypothesis), there is a probability of correctly rejecting the null hypothesis. a. Increasing the power can be done by increasing sample size, the Type I error, and by moving further away from the null hypothesis value. Hypothesis Testing for a …

8.what is the probability that a test correctly rejects a false null hypothesis​ called?

Null Hypothesis(H0): Average =99%. Alternate Hypothesis(H1): Average is not equal to 99%. Note: When we test a hypothesis, we assume the null hypothesis to be true until there is sufficient evidence in the sample to prove it false. In that case, we reject the null hypothesis and support the alternate hypothesis.

Hypothesis Testing: A Way to Accept or Reject Your Hypothesis Using p-value

9.what is the probability that a test correctly rejects a false null hypothesis​ called?

By analogy, we reject a true null hypothesis and accept a false alternative hypothesis. Type II error: The jury says a person is not guilty when he or she really is. By analogy, we fail to reject a null hypothesis that is false. In other words, we do not accept an alternative hypothesis when it is really true. Let’s Summarize

Hypothesis Testing (5 of 5)

10.what is the probability that a test correctly rejects a false null hypothesis​ called?

probability that it correctly rejects a false null hypothesis. If power is high, we can be confident we’ve looked hard enough. A hypothesis test was performed which resulted in a p-value of .40.
