None of the available answers are correct: Choices a. and b. are automacally disqualiﬁed since they state the hypotheses in terms of sample stascs – hypothesis statements are about populaons. Choices b. and d. are automacally disqualiﬁed since they state the hypotheses in terms of proporons, not averages. Further, the professor does not spulate

The average of the 3 rd sample would increase by 30, causing more “spread” between the 3 sample averages. The variance withinin the 3 rd sample would not change. The net result is a larger MSB (we don’t have enough information to determine by how much) while the MSE remains the same.
