Related-Samples T-Test Mean Pair 1 Before After-4.50000 Std. Deviation 3.20936 c. Now look at the p-value. Paired Samples Test Paired Differences Std. Error Mean 1.31022 95% Confidence Interval of the Difference Lower -7.86802 Upper t -1.13198 -3.435 5 Sig (2-tailed) 019 2. Look at the above Related-Samples t-Test SPSS output and use it to answer the following questions. a. Recall that we have always used a test value of zero for the Related-Samples t-test. Therefore, compare that test value with the 95% C.I. given on the SPSS output. Is that test value inside the interval or outside the interval? Inside or Outside interval?_ b. Based your answer to part (a), do you think that a two-tailed hypothesis test using alpha- .05 would Reject Ho? (No credit unless your answer is consistent with your answer to part a). Would a two-tailed, a = .05 hypothesis test Reject Ho? Yes or No: Based on the p-value, do you Reject HO? Yes or No: Do your C.I. and p-value answers match? (If they don't match, you've made a mistake in interpeting p-values, C.I.'s, or both. Figure out how to fix it before the exam!)
