Verified Answer
HA: p ≠ 0.62 represents the alternative hypothesis that the proportion of students graduating in four years is not equal to 0.62 in the population.
This is the appropriate hypothesis test as we want to determine if there is a significant difference between the observed proportion of 0.62 and the true population proportion.
