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?
a. h0: p = 0.59; ha: p ≠ 0.59
b. h0: p = 0.59; ha: p > 0.59
c. h0: p = 0.78; ha: p ≠ 0.78
d. h0: p = 0.78; ha: p > 0.59

Option b

Step-by-step explanation:

Given that 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%.

we have to find whether  taking a class in a short-term format (8 weeks instead of 16 weeks) increase a student’s likelihood of passing the course

Since pass rate for 16 weeks is 59% we check whether for 8 weeks is more than this.

So correct null and alternative hypotheses for this research question

would be:

b.H0: p = 0.59; Ha: p > 0.59

Option b is right.
