Question

Smart Driver Driving School conducted a study comparing two teaching methods. In a random sample, 77 out of 100 students who received the conventional teaching method passed the road test, and 84 out of 100 students who received the new teaching method passed. What are the appropriate null and alternative hypotheses?

a. Null: Conventional method pass rate = New method pass rate, Alternative: Conventional method pass rate ≠ New method pass rate
b. Null: Conventional method pass rate > New method pass rate, Alternative: Conventional method pass rate ≤ New method pass rate
c. Null: Conventional method pass rate < New method pass rate, Alternative: Conventional method pass rate ≥ New method pass rate
d. Null: Conventional method pass rate = New method pass rate, Alternative: Conventional method pass rate < New method pass rate

Answer 1

The appropriate null and alternative hypotheses for this study are: Null: Conventional method pass rate = New method pass rate, Alternative: Conventional method pass rate ≠ New method pass rate.

Step-by-step explanation:

The appropriate null and alternative hypotheses for this study are:

a. Null: Conventional method pass rate = New method pass rate,

Alternative: Conventional method pass rate ≠ New method pass rate

To compare the teaching methods, we are testing to see if there is a difference in the pass rates between the conventional and new methods.

The null hypothesis assumes that there is no difference, while the alternative hypothesis suggests that there is a difference.
