• z-score (standardization): If the population parameters are known, then rather than computing the t-statistic, one can compute the z-score; analogously, rather than using a t-test, one uses a z-test. This is rare outside of standardized testing. • Studentized residual: In regression analysis, the standard errors of the estimators at different data points vary (compare the middle versus endpoints of a simple linear regression), and thus one must divide the different residuals by diffe… WebA. A two-sample t-test. B. A paired t-test. C. A pooled t-test. D. An unpooled t-test. 16. Assuming the conditions are met, based on the t-statistic of 1.80 the appropriate conclusion for this test using α = .05 is: (Table would be provided with exam.) A. Df = 14, so p-value < .05 and the null hypothesis can be rejected.
