In general, it is the equality hypothesis: eg. “the two populations have the same mean”. The alternative hypothesis H₁ negates the null hypothesis: eg. “the mean in the second population is higher than in the first”. WebJun 11, 2024 · You know that the test statistic under the null hypothesis has distribution. T ∼ Exp ( n) = Exp ( 15) The weight of the tail of this distribution is. P ( T > t) = exp ( − 15 t) We reject null at significance level. α ≤ P ( T > t) = exp ( − 15 t) p-value is maximum significance level at which we reject null, so.
