3 ) If the p- value is less than a in a two - tail test Al the null hypothesis should not be rejected B ) the null hypothesis should be rejected Ca one- tail test should be used D / no conclusion should be reached 4 ) If you know that the level of significance all of a test is 596 , you can tell that the probability of committing a Type II error ( 8 ) is A ) 2.596 B ) 959 6 C 97 596 D ) unknown 5 ) The standard error of the mean A ) is never larger than the standard deviation of the population B ) decreases as the sample size increases C ) measures the variability of the mean from sample to sample D ) All of the above
