Ayla, a recent graduate from UT Austin with a Ph.D. in Psychology, is planning an in-person celebration with family and friends to mark the achievement. She cannot decide on which family recipe to bake for the occasion: either Great Grandma Julie's apple pie or Great Grandma Irma's lemon meringue pie. To help her decide, Ayla recruits 12 members of her lab to taste small samples of both desserts and rate their deliciousness on a scale from 1 (yucky) to 9 (yummy). The following table shows the results of a repeated-measures ANOVA comparing the taste ratings of the two pies. Note that several values are missing in the table. What is the missing value for SS_total?
