Question

Open Lab Visits data. Is it reasonable to claim that students with 8 or more visits to open lab sessions have average final grade higher than students with less than 8 visits? 1. What test/procedure did you perform? (5 points)

Answer 1

Answer: The test/procedure that was performed was the One-sided t-test.

Explanation:

The one-sided t-test was performed because they were checking if the average of one variable is larger than the average of the other variable used.

The  P-value/margin of error is 3.59609E-07 and the statistical interpretation of this is the value of the P-value was much smaller than 5%. This let the test result conclusive.

The other test that is performed in some of these cases are called the two-sided t-test.
