Question

The hypothesis should be identified with the hypothesis of no change, no difference, no improvement, and so on. A error involves not rejecting the null hypothesis H_0 when H_0 is false. If the P-value is larger than the level of significance alpha then the researcher should at level alpha. Which of the following statements are not correct? Circle the letter of the correct choice It is possible that the null hypothesis may be rejected when it is true. It is impossible that the null hypothesis may be rejected it is true. It is possible that the null hypothesis may not be rejected when it is false. All of the above statements are correct. None of the above statements are correct. Which of the following P-values will lead us to reject the null hypothesis at the .05 level? Circle the letter(s) of the correct choice(s). There may be more than one. .025 .075 .10 .15 Any P-value greater than .05

Explanation / Answer
