(a) The value of the standardized test statistic: Note: For the next part, your answer should use interval notation. An answer of the form (−[infinity],a) is expressed (-infty, a), an answer of the form ( b ) is expressed (b, infty), and an answer of the form (−[infinity],a)∪(b,[infinity]) is expressed (-infty, a) ∪(b, infty). (b) The rejection region for the standardized test statistic: (c) Your decision for the hypothesis test: A. Reject H1​. B. Do Not Reject H0​. C. Do Not Reject H1​. D. Reject H0​.
