Question

A professor of statistics refutes the claim that the average student spends 6 hours studying for the final. To test the claim, the hypotheses H0: $\mu$ = 6, HA: $\mu$ < 6 should be used.

Quizplus · Accepted Answer

The correct null hypothesis (H0) should state there is no difference from the claim, thus H0: μ = 6. The alternative hypothesis (HA) correctly reflects the professor's belief that students study less than 6 hours, so HA: μ < 6. The symbols in the original statement seem to be incorrectly formatted or misinterpreted.
