What is an advantage of using a related-samples t-test over an independent-samples t-test? There is a carry-over effect with the related-samples t-test .None of the options. The related-samples t-test needs less participants. There is a maturation effect in the related-samples t-test.

For each example, state whether the one-sample, the two-independent-sample, or the related samples t-test is most appropriate. If it is a related samples t-test, indicate whether the test is a repeated measures design or a matched-pairs design. 1) A researcher matches right-handed and left-handed siblings to test whether right-handed siblings express greater emotional intelligence than left-handed siblings. A. one-sample t-test B. two-independent sample t-test C. related samples t-test using the repeated measures design D. related samples t-test using the matched-pairs...

Imagine that a researcher is conducting a paired-samples t test. She finds that the sample mean difference is 5, the standard deviation of the difference scores is 15, and the sample size is 85. The researcher is also using a typical null hypothesis that proposes no differences between the relevant population means. Under these circumstances, what is the value of the paired-samples t statistic? Please retain a minimum of three decimal places for all steps (if relevant) and provide a...

Compare and contrast the differences between a single sample t test and an independent samples t test. Next describe a hypothetical study using the design of an independent samples t test. List the two groups that you would test.

A t statistic of 1.2 is computed from a large simple random sample of 10,000 observations to test a null hypothesis H0: μ-O, against an alternative Ha. The test is performed at a level of significance of 0.05. what is the corresponding p-value if the alternative is Ha: μ+0 ? (not equal to zero) Hint: For large samples, the t-statistic follows the N(O,1) distribution just as the z-statistic

Find the standardized test statistic, t, to test the claim that μ1 < μ2. Two samples are random, independent, and come from populations that are normally distributed. The sample statistics are given below. Assume that two populations' variance is the same (σ21= σ22). n1 = 15 n2 = 15 x1 = 25.76 x2 = 28.31 s1 = 2.9 s2 = 2.8
