Statistical inference Hypothesis testing ScienceDirect. What is the appropriate statistical decision with respect to the null hypothesis that the population variance is equal to 625 tested against the alternate hypothesis that it is not equal to 625 if the desired level of significance is 10%? a) Reject the null hypothesis b) Do not reject the null hypothesis c) Reject both hypotheses d) Accept both hypotheses e) Test inconclusive.5 Testing, In general, each test calculates a test statistic, that must be interpreted with some background in statistics and a deeper knowledge of the statistical test itself. Tests also return a p-value that can be used to interpret the result of the test. The p-value can be thought of as the probability of observing the two data samples given the base assumption (null hypothesis) that the two samples.
