Null hypothesis: μ 1 - μ 2 = 0. Alternative hypothesis: μ 1 - μ 2 ≠ 0. Note that these hypotheses constitute a two-tailed test. The null hypothesis will be rejected if the difference between sample means is too big or if it is too small.

WebSo you set Null-Hypothesis H 0 := new treament is equal or worse than placebo and Alternative Hypothesis H 1 := new treatment is better than placebo. This because in the course of a statistical test you either reject the Null-Hypothesis (and favor the Alternative Hypothesis) or you cannot reject it. WebHere, both null and alternative hypotheses are simple since mean and variance are sufficient to completely specify a normal distribution. The maintained hypothesis in this case is that H;θ ∈{1,2}.
