1. For a two-tailed, independent samples t-test, the alternative hypothesis would look like μ1−μ2≠0, whereas the null hypothesis would look like μ1−μ2=0. True or False?

2. When the null hypothesis is true, the mean of the sampling distribution of differences between means is equal to the mean of the population that the samples represent. True or False?

3. In a related-samples t-test, if there is no treatment effect we expect that μD will equal 0 (zero). True or False?

Consider the hypothesis test with null hypothesis μ1=μ2 and alternative hypothesis μ1 > μ2.Suppose that sample sizes n1 = 10 and n2 =10, that the sample means are 4.9 and 2.8 respectively, and that the sample variances are 2 and 3 respectively. Assume that the population variances are equal and that the data are drawn from normal distributions. a) Test the hypothesis that at α= 0.05 and provide a conclusion statement b) Provide an adequate confidence interval with 95% confidence...

Below you will find the null and alternative hypothesis for an ANOVA: H0: μ1 = μ2 = μ3 H1: at least one of the means is different. For Data Set B, based on the p-value and F vs. F critical values we found above, do we fail to reject the null hypothesis? Or, do we reject the null hypothesis? Group of answer choices Fail to Reject Reject Using Data Set B, run the Single Factor ANOVA in Excel, as we...
