A professor of linguistics refutes the claim that the average student spends 3 hours studying for the midterm exam. She thinks they spend more time than that. Which hypotheses are used to test the claim? A)H ₀: m ¹ 3 vs. H ₁: m > 3 B)H ₀: m = 3 vs. H ₁: m ¹ 3 C)H ₀: m ¹ 3 vs. H ₁: m = 3 D)H ₀: m = 3 vs. H ₁: m 3

Quizplus · Accepted Answer

The correct hypothesis setup for testing if students spend more than 3 hours studying is to have the null hypothesis (H0) state the claim to be tested (in this case, m = 3) and the alternative hypothesis (H1) reflect the professor's belief (m > 3). However, due to a formatting error, the correct representation of the hypotheses is not clearly shown. The intended correct answer seems to be A, where the null hypothesis would typically be m = 3 (claim to be tested), and the alternative hypothesis would be m > 3 (professor's belief). The symbols and formatting are incorrect due to a transcription error, but the logic of choice A aligns most closely with the correct hypothesis testing approach.
