1. Consider the following conditions for various kinds of two-sample t-tests, and in each case, given the provided information, compute the p-value associated with the stated hypotheses. In each case, tcalc or zcalcrepresents values of the test statistic computed using standard formulas with sample values for means (or proportions) and the appropriately computed standard errors, and “n” refers to the sample size. In all cases, if degrees of freedom (d.f.) is required, use the following formula:d.f. = min(n1 - 1, n2 - 1)

a. H0: 1 - 2 0 H1: 1 - 2 > 0 tcalc = 2.1, n1 = 8, n2 = 8

Explanation / Answer

a.Here it is given that  H0: 1 - 2 0 H1: 1 - 2 > 0

Also tcal=2.1 and it is right tailed test

So P value for 7 df is 0.037
