If the null hypothesis is rejected when the null hypothesis is true, what type of error, if any, has been made? Type I error Type II error Correct decision Type error
If the null hypothesis is rejected when it is false, this is called O an alternative hypothesis O a type I error O the correct decision O a type II error
A Type II error is committed when a. a true alternative hypothesis is mistakenly rejected. O b. the true null hypothesis is correctly rejected. C. a true null hypothesis is mistakenly rejected. d. the true alternative hypothesis is correctly rejected.

You are testing the null hypothesis µ=150 versus the two tailed alternative. You reject the null hypothesis in favor of the alternative hypothesis. If in reality, µ does equal 150, you have made a : A. Correct Decision B. Type II Error C. Type I Error
In a two-tail test for the population mean, if we decided in favor of the alternative hypothesis when the null hypothesis is false, A. a Type II error is made B. a one-tail test should be used instead of a two-tail test C. a correct decision is made D. a Type I error is made In a one-tail test for the population mean, if we decide in favor of the null hypothesis when the alternative hypothesis is true, A. a...
11. If the null hypothesis is rejected at a 05 significance level, it (a) must also be rejected at a.10 significance level. (b) might also be rejected at a .10 significance level. (c) must not be rejected at a.10 significance level. (d) none of the above lfte null hypothesis İs not rejected at a .05 significance level, it: (a) will also not be rejected at a.01 significance level. (b) might be rejected at a .01 significance level. (e) will be...
When a false null hypothesis is not rejected, a.we commit a type i error b. we choose the wrong alpha c. we commit a type ii error d. we commit a type ii error e.we rely on the p value to see the probability of the null hypothesis being correct
A Type II error occurs in hypothesis testing when we _____________________________. fail to reject the null hypothesis and the null hypothesis is not true reject the null hypothesis and the null hypothesis is true fail to reject the alternative hypothesis and the alternative hypothesis is not true reject the alternative hypothesis and the alternative hypothesis is true
If in reality (i.e., nature) the null is true, but the research rejects the null hypothesis, the researcher has made a _____________. a. Type I Error b. Type II Error c. Correct conclusion and Power has been found d. Potentially correct conclusion
