An alpha (significance) level is set at .05 for a research study, What does this mean?

A. A researcher is willing to reject the null hypothesis if the probability of the null hypothesis being true is lower than .05.

B. A researcher is willing to reject the null hypothesis if the probability of the alternative hypothesis being true is lower than .05.

C. A researcher is willing to reject the null hypothesis if the probability of the null hypothesis being true is higher than .01.

D. A researcher is willing to reject the alternative hypothesis if the probability of the null hypothesis being false is higher than .01.

True or False 1. Hypothesis tests are robust to the significance level you choose, meaning regardless of the alpha level: .10, .05, or .01, our test will have the same conclusion or result. 2. If alpha is greater than the p-value, then we reject the null hypothesis. 3. The p-value is strictly the probability the null hypothesis being true. 4. Hypothesis tests are accessing the evidence provided by the data and deciding between two competing hypotheses about the population parameter....

A. -1.65 B. -1.96 C. -2.33 D. +/- 1.65 If the probability of finding a difference that really does exist is .65 (correctly rejecting the null hypothesis when the null hypothesis really is false), what is the probability of the Type II error?

True or False: The higher the level of significance of a hypothesis test, the stronger the evidence we require to reject the null hypothesis. True or False: The purpose of a hypothesis test is to assess the evidence in favour of the null hypothesis. True or False: The higher the p-value of a hypothesis test, the more evidence we have to reject the null hypothesis.
