Short-term classes: Does taking a class in a short-term format (8 weeks instead of 16 weeks) increase a student's likelihood of passing the course? For a particular course, the pass rate for the 16-week format is 59%. A team of faculty examine student data from 40 randomly selected accelerated classes and determine that the pass rate is 78%.

Which of the following are the appropriate null and alternative hypotheses for this research question?

1. H0:p=0.59; Ha:p0.59
2. H0:p=0.59; Ha:p>0.59
3. H0:p=0.78; Ha:p0.78
4. H0:p=0.78; Ha:p>0.59
