A researcher is interested in knowing if music impacts how students perform on tests. Specifically, she tests whether the type of music played (country vs. rock) as well as whether or not lyrics are present have an impact on math test scores. She randomly selects a total of 24 kids of the same ability level (n = 6 per cell) to be in each of the conditions represented below. The mean number of correct responses per group has been given, as well as the marginal means, grand mean, and the standard deviations per group. Use a = 0.05 for all omnibus F tests. Music Type Marginal Means Country Rock x = 8 x = 18 No Lyrics $2 = 5.5 $2 = 7.5 x = 13 Lyric Content x = 14 x = 16 Lyrics $2 = 6.5 $2 = 4.5 x = 15 Marginal Means x = 11 x = 17 x = 14Complete the Source Table. The Sum of Squares Total has been given to you as a guide; if your values in that column do not add up to the given value, please check your work. Calculated values should be whole numbers if you doing your work correctly; report the F critical values to 2 decimals. Use a = 0.05. Write 1 in the last column ifthere is a statistically signicant effect. Otherwise, write 0. Source SS df MS F F cm Signicant? Lyric Content Music Type Interaction Error Total 456
