The correct sequence is 2,3,5,4,1. First, the team must specify the parameter to be tested so the hypothesis is clearly tied to the characteristic of interest, such as a mean, proportion, or variance. Second, the appropriate test statistic is selected based on the type of data, assumptions, and problem structure. Third, the rejection criteria are defined, which includes establishing the significance level and the rule for deciding whether the null hypothesis will be rejected. Fourth, the critical values are calculated from the relevant statistical distribution. Finally, once the observed test result is compared with the decision rule, the team draws a conclusion. This sequence reflects disciplined statistical reasoning in the Analyze Phase. The team must know what it is testing before choosing the method, and it must establish the decision logic before interpreting results. In Black Belt practice, following a correct testing sequence helps avoid errors in hypothesis formulation and decision-making. Therefore, the correct answer is B, 2,3,5,4,1, because it matches the standard logical order for conducting a hypothesis test.
