Please help, I've been stuck on this question for 2 days.... I need step by step instructions.

Seasonal affective disorder (SAD) is a type of depression during seasons with less daylight (e.g., winter months). One therapy for SAD is phototherapy, which is increased exposure to light used to improve mood. A researcher tests this therapy by exposing a sample of patients with SAD to different intensities of light (low, medium, high) in a light box, either in the morning or at night (these are the times thought to be most effective for light therapy). All participants rated their mood following this therapy on a scale from 1 (poor mood) to 9 (improved mood). The hypothetical results are given in the following table. --- 5 Morning Time of Day Night w-h-HONWU'lmmHJ-h-O'a cacm-Jooooaxoo-no'm mummucmmommu (a) Complete the Ftable and make a decision to retain or reject the null hypothesis for each hypothesis test. (Round your answers to two decimal places. Assume experimentwise alpha equal to 0.05.)

Retain the null hypothesis. .J Reject the null hypothesis. (b) Compute Tukey's HSD to analyze the signicant main effect. The critical value is for each pairwise comparison
