A researcher uncovers that there is a significant interaction between the factor of marital status (i.e., married or non-married) and participant sex (i.e., male or female) regarding well-being among a sample with n = 6 participants in each condition. A researcher decides to compare the difference in well-being between married men and women. The MSwithin treatments from the original two-factor analysis is MSwithin treatments = 1.00. What is the F-ratio for this comparison using the matrix below, which depicts descriptive statistics regarding married participants? ​ __________________________________________________________________________________________ ​                                         Participant Sex ​   Males                                                                      Females __________________________________________________________________    n = 6                                                                         n = 6                       N = 12  M =  4                                                                      M = 5                       G = 54  T = 24                                                                       T = 30     a.
