An industrial psychologist would like to see if one’s ability to solve problems changes with the time of day.
Null Hypothesis and Research Hypothesis?
Null: The time of day has no significant effect on the time taken by employees to solve a complex problem.
Research: The later in the day, the longer it takes employees to solve a complex problem.

An industrial psychologist would like to see if one’s ability to solve problems changes with the time of day.
What is the IV and DV?
IV: The time of day
DV: The ability to solve problems. This could either focus on an accurate response or the amount of time taken to solve the problem.
