I need help solving this problem. A psychologist is studying the effect of sleep deprivation on reaction times. Participants were asked to complete a reaction time task after three conditions: (1) a full night's sleep, (2) 24 hours of sleep deprivation, and (3) 48 hours of sleep deprivation. Reaction times (in milliseconds) for each condition were recorded as continuous variables. The researcher hypothesizes that sleep deprivation will significantly impact reaction times. Please provide the following:

A) What statistical test would you conduct to analyze the data? Explain why this test is appropriate.

B) Write the hypotheses for the test you selected. Clearly state the null and alternative hypotheses (APA guidelines).

C) If you were to run this test in JAMOVI, how would you check assumptions (e.g., sphericity) and what would you do if they are violated.

Please respond in paragraph format as if reporting them in a journal article, following APA guidelines. Thank you.
