3. Times are tough for Luis leet. In desperation, he recently got a job singing outdated Disney songs at a piano bar just off the Las Vegas strip. His boss is demanding that he constantly update his song list based on the response he gets from his audience (who are rating his performance on the software platform InstaTrash). Still clinging to the glory days, Luis still believes that all of his songs are equally awesome, but his boss thinks that at least one of his songs will be rated differently than the others.. Below are the scores he received from five patrons. Using ANOVA, conduct an F-test to see who's right. Each score is out of ten, where ten is the highest possible rating.

What is F_observed

who is correct, Luis or his boss?
