If we reject a null hypothesis at the 0.05 level of significance, then we must also reject it at the 0.10 level.
举一反三
- Using the confidence interval when conducting a two-tail test for the population mean we do not reject the null hypothesis if the hypothesised value for µ:
- If the p-value of a test statistic is .20 and the level of significance is .05, the null hypothesis should be rejected.
- What happens to the rejection region if the level of significance is changed from 0.10 to 0.05?
- The critical region is: A: the region in which our sample statistic must fall if we are going to be certain to make a Type I error. B: the region in which our sample statistic must fall if we are not to reject the null hypothesis. C: the region in which our sample statistic must fall if we are going to be certain to make a Type II error. D: the region in which our sample statistic must fall if we are to reject the null hypothesis.
- When we conduct cultural analysis of the anti-pandemic situation in different countries, we should clarify the level of cultural analysis and ensure that the comparison is made at the same level. A: 正确 B: 错误
