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. There are two hypotheses involved in hypothesis testing Null hypothesis H 0: It is the hypothesis to be tested . 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. If the biologist set her significance level \(\alpha\) at 0.05 and used the critical value approach to conduct her hypothesis test, she would reject the null hypothesis if her test statistic t* were less than -1.6939 (determined using statistical software or a t-table):s-3-3.
