WebTo decide whether the null hypothesis is to be rejected or accepted, we need to compare the test statistic with the critical value of the test at the given level of significance. Since the question does not provide the details of the hypothesis test or the critical value, it is not possible to determine the correct answer with only the test statistic of 2.35. WebWhat we have shown instead is that assuming the null hypothesis is true, the conditional probability that the sample data exhibits the obtained test statistic is 0.04; i.e. P ( D H 0) =.04 where D = the event that the sample data exhibits the observed test statistic.
