Assume that you want to test the claim that the paired sample data come from a population for which the mean difference is
μd=0
Compute the value of the t test statistic. Round intermediate calculations to four decimal places as needed and the final answer to three decimal places as needed.

Let's now perform a mean-matched pairs test to test the claim that there is no mean difference between the age of males and females. For the context of this problem, d=x2−x1where the first data set represents actress (female) ages and the second data set represents male (actor) ages. We'll continue to use a significance of 0.05. You believe the population of difference scores is normally distributed, but you do not know the standard deviation. H0: μd=0 H1:μd≠0 Actress Age Actor...
Test the claim about the mean of the differences for a
population of dependent (paired) data at the level of significance
α. Please remember to include all 5 parts of a hypothesis test
mentioned in the module summary. Assume the samples are random and
dependent, and the populations are normally
distributed.

7) Determine the decision criterion for rejecting the null hypothesis in the given hypothesis test ie, describe the values of the test statistic that would result in rejection of the null hypothesis Suppose you wish to test the claim that the mean value of the differences d for a population of paired data, is greater than 0. Given a sample of n-15 and a significance level of a-001, what criterion would be used for rejecting the null hypothesis...
