You hypothesize that people who play brain teasers are smarter than people who do notplay brain teasers. You compare intelligence scores in three groups: Sudoku Players,Crossword Players, and people who do not play brain teasers. The data is as follows: Sudoku Players ===== #100 101 102 103 104 105 108 110 113 100 Crossword Players ================== #103 104 103 #104 #105 #108 110 106 #105 104 No Brainteasers #85 100 #120 #115 100 #103 102 100 100 95 The sum of squares een samples for the data is 57.9 and the sum of squares within groups is 1070.0. What is the Mean of Squares within samples? Calculate to the nearest hundredths place (two decimal places).
