Consider each of the statements below. For each statement, decide whether it is sometimes, always, or never a true statement. v 1. In a hypothesis test, the direction of the alternative hypothesis (right-tailed, left-tailed, or two-tailed) atfects the way the p-value is computed. v 2. If Marcus takes a random sample of a population and conducts a hypothesis test and Caroline takes a different random sample of the same population and conducts the same hypothesis test, they will have the same observed effect sizes. 3. A hypothesis test that produces a positive test statistic will produce a positive effect size. v 4. In general, increasing the sample size in a statistical study will decrease the standard error of the statistic computed from the sample. v 5. A hypothesis test of a single population mean that produces a t-test statistic /=0 will produce an effect size d0.
