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. Webtest investigates whether there are significantly more “yes” than “no” responses. There are two tests designed for this circumstance. One of these tests is a z test that is very …
