Question:
The article “Hitting a High Note on Math Tests: Remembered Success Influences Test Preferences” (J. of Exptl. Psych. 2016: 17–38) reported a study in which 130 participants were administered two math tests (in random order): a shorter, more difficult exam and a longer, easier one. Participants were then asked to estimate how much time they had spent on each exam. Let μ̃ denote the true median difference in time estimates (short test minus long test). Test the hypotheses H0: μ̃D = 0 versus Ha: μ̃D > 0, with Ha supporting the psychological contention that people perceive easier tasks to be quicker, using a sign test based on the fact that 109 participants gave positive differences and 21 gave negative differences.
