Which of these is NOT something the conclusion sentence of an inference answer must contain?

Answer

The value of the test statistic to two decimals

Options - A. The value of the test statistic to two decimals - B. The parameter the decision is about, in words - C. The direction of the evidence, in business terms - D. The significance level the decision was made at Why - A. Correct — the statistic value earned its mark at step two; the conclusion sentence names parameter, direction, α and setting, not the arithmetic. - B. "The mean days-to-pay" is the parameter; without it the sentence says nothing about what was decided. - C. "Below 45 days" is the direction; "reject H0" alone is a decision, not a conclusion. - D. "At α = 0.05" is the level; a conclusion without it cannot be checked against the table mark.
