Answer: C
The correct order of the steps is: state the research hypothesis, state the null hypothesis, select a probability of error level, select and compute the test, and interpret the results, so d, e, c, b, a.
The null hypothesis follows from the research hypothesis, and alpha is fixed before the test is calculated so that the result does not influence the decision.
Options A and B start with interpretation or put alpha before the null hypothesis, and option D puts the null hypothesis ahead of the research hypothesis.
