Quizplus · Accepted Answer

The null hypothesis (H0) should reflect the claim being tested, which is that the average starting salary is at least $47,413. Therefore, H0: μ ≥ $47,413. The alternative hypothesis (HA) is the opposite of the null, which is that the average starting salary is less than $47,413, HA: μ < $47,413.
