Suppose samples of six different brands of diet or imitation margarine were analyzed to determine the level of physiologically active polyunsaturated fatty acids (PAPUFA, in percent), resulting in the data shown in the accompanying table. Imperial 14.1 13.6 14.6 14.3 Parkay 12.8 12.5 13.5 13.0 12.3 Blue Bonnet 13.5 13.4 14.1 14.4 Chiffon 13.2 12.7 12.6 14 Mazola 16.8 17.3 16.4 17.3 18.0 Fleischmann's 18.1 17.2 18.9 18.4 w USE SALT (a) Test for differences among the true means for PAPUFA percentages among the different brands. Use a = 0.05. Calculate the test statistic. (Round your answer to two decimal places.) F = 70.20 | X Use technology to find the P-value. (Round your answer to four decimal places.) P-value = 0.0000 P What can you conclude? O Fail to reject Ho. There is convincing evidence that the mean PAPUFA percentages for the six brands are not all equal. O Fail to reject Ho. There is not convincing evidence that the mean PAPUFA percentages for the six brands are not all equal. Reject Ho. There is convincing evidence that the mean PAPUFA percentages for the six brands are not all equal. O Reject Ho. There is not convincing evidence that the mean PAPUFA percentages for the six brands are not all equal.

There is not convincing evidence that the mean PAPUFA percentages for the six brands are not all equal. (b) Use the T-K procedure to calculate 95% simultaneous confidence intervals for all differences between means. (Round your answers to three decimal places.)
