for a test of a mean, which of the following is incorrect?
Ā
| H0Ā is rejected when the calculatedĀ p-value is less than the critical value of the test statistic. |
| In a right-tailed test, we rejectĀ H0Ā when the test statistic exceeds the critical value. |
| The critical value is based on the researcher's chosen level of significance. |
IfĀ H0:Ā %u03BCĀ %u2264 100 andĀ H1:Ā %u03BCĀ > 100, then the test is right-tailed.
Choose the best answer.
Suppose you collect a sample that has a mean of 37 with a 99% confidence interval of [32,42], and you are interested in the hypothesis test below at the Ī±=0.05 level.
| H0: Ī¼=43 |
| Ha: Ī¼ā 43 |
a) You should ask for more information because the sample size and standard deviation are needed for a hypothesis test of this kind.
b) You should fail to reject the null hypothesis because the p-value is greater than 0.05.
c) You should ask for more information because the confidence interval does not match the Ī±Ī± level.
d) You should reject the null hypothesis because the p-value is less than 0.05.
