Conscientiousness is a tendency to show self-discipline, act dutifully, and aim for achievement. The trait shows a preference for planned rather than spontaneous behavior. A random sample of 650 students is asked to fill out the Hogan Personality Inventory (HPI) to measure their level of conscientiousness. The 350 graduate students had a mean score of 153 with a standard deviation of 21. The 300 undergraduate students scored an average of 148 with a standard deviation of 16. We are interested in determining whether graduate students score higher, on average, on the HPI than undergraduate students. What are the appropriate null and alternative hypotheses? O Ho: HG HUG # 0 and Ha: HG- HUG = 0 Ho: HG HUG= 0 and Ha: HG- HUG < 0 O Ho: HG HUG = 0 and Ha: HG- HUGO O Ho: HG HUG = 0 and Ha: HG- HUG > 0

![Conscientiousness is a tendency to show self-discipline, act dutifully, and
aim for achievement. The trait shows a preference for planned rather than
spontaneous behavior. A random sample of 650 students is asked to fill out
the Hogan Personality Inventory (HPI) to measure their level of
