I can not figure this out please help! There is a second part I am attaching as another question too.

C https://www.webassign.net/web/Student/Assignment-Responses/submit?dep=21801080&tags=autosave K 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 SAD patients 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. Light Intensity Low Medium High Morning 5 5 7 6 6 8 3 4 6 7 7 9 5 9 5 Time of 6 7 8 Day Night 5 6 9 8 8 7 6 7 w C0 10 UT Co UT 6 (a) Complete the F-table 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.) Source of Variation SS MS F Time of day Intensity Time of day x Intensity Error Total State the decision for the main effect of the time of day. Retain the null hypothesis. MacBook Air F2 20 888 FA
