WebThe TOST approach can also be used for a one-sample test (and similarly for a two dependent sample test). In this case, we test the equivalence between the mean of a single population and some hypothetical mean μ0. H0: μ – μ0 ≤ θL or μ – μ0 ≥ θU. H1: θL < μ – μ0 < θU. This time we conduct two one-sample t-tests. WebTo test Hypothesis 2, we ran regressions on subsamples partitioned by family firms versus non-family firms. A firm was classified as family firm if the executive directors hold more than 20% equity ownership [90,128,129]. To test Hypothesis 3, subsample regressions were performed on firms audited by the Big Four versus non-Big Four auditors. ... next collingwood match
