WebFeb 28, 2024 · Hypothesis 2 is a comparison of 2 sample means (the mean of X 1 and the mean of X 2 ): H0: μ1 = μ2 H1: μ1 ≠ μ2. The test variable will therefore be m 1 − m 2 σ 1 2 n 1 + σ 2 2 n 2. Please note that the 2 hypothesis can only be compared if n 1 = n 2, else the mean of X 1 − X 2 have no sense. In the numerator, we have the same thing ...
WebBecause T 1, and T 2 are less than the quantile of the Student t-distribution, t 0.975 (4) = 2.7764, both tests lead to a conclusion that H 0: β 2 = 0, β 1 = 0.148 should be accepted. This conclusion is, however, false. The more rigorous approach uses a simultaneous test of the composite hypothesis H 0: β 2 = 0 and β 1 = 0.148. greenwell chisholm owensboroWebthe value specified by H0 is called a two-sided (or two-tailed) test, e.g. H0: µ = 100 HA: µ <> 100 I. Whether you use a 1-tailed or 2-tailed test depends on the nature of the problem. Usually we use a 2-tailed test. A 1-tailed test typically requires a little more theory.
