The significance level of .05, the z-statistic and a cardinal-tailed scrutiny was employ to determine the truth of the hypothesis. For week four the squad is to use the same information to conduct an equivalent, nonparametric canvass of hypothesis. Nonparametric tests makes less rigid demands of the info.
