Compute the values identified below (to 2 decimals, if necessary). Sum of Squares, Treatment   Sum of Squares, Error   Mean Squares, Treatment   Mean Squares, Error   Calculate the value of the test statistic (to 2 decimals, if necessary).   The -value is   What is your conclusion?   b. Use Fisher's LSD procedure to compare the comfort levels of nonbrowsers and light browsers. Use . Compute the LSD critical value (to 2 decimals).
