Employees at a company are asked to work from home for two weeks and their average productivity is measured. The employees then work at the office for two weeks and their productivity is measured again to see if working from home is better for productivity.

Question

Which type of hypothesis test is appropriate for this situation?

Hypothesis test for two independent means
Hypothesis Test for two paired (dependent) means
Hypothesis Test for one mean
Not enough information to tell

Answer 1

In this situation, you are comparing the productivity of the same group of employees under two different conditions: working from home and then working in the office. Since you are measuring the same subjects (employees) under both conditions, the data is paired or dependent.

Therefore, the appropriate hypothesis test for this situation is:

Hypothesis Test for two paired (dependent) means.
