Since the biologist's test statistic, t* = -4.60, is less than -1.6939, the biologist rejects the null hypothesis. The objective we set our Hypothesis Testing is basically an assumption that we make about the population parameter. ANSWER . If ˚(X) is any test of a hypothesis concerning , then (T) given by (t) = E[˚(X) jT = t] is a test depending on T only and its power is identical with that of ˚(X). So, the calculation of test statistic can be done as follows-T= µ/(s/√n) =.0013/ (.0045/√50) Test Statistic will be – The test statistic is = 2.04. The work of these two authors, both of whom died in 2000, spans the achieve-ments of statistics in the second half of the 20th century, from model-free data analysis to the most abstract and mathematical asymptotic theory. Since the value of the test statistic is less than +2.33, then the null hypothesis cannot be rejected for a 1% level of significance.
