Samples of six different brands of dietimitation margarine w

Samples of six different brands of diet/imitation margarine were analyzed to determine the level of physiologically active polyunsaturated fatty acids (in percentages), resulting in the following data: Obtain the ANOVA table. Assess the null hypothesis that there are no difference in the mean levels of physiologically active polyunsaturated fatty acids. State the hypotheses, Give the value of the test statistic. Obtain the P value, giving the degrees of freedom. State a conclusion in the context of the problem. Plot the residuals versus the brands and comment. Show the QQ plot of the residuals and comment. Use the Bonferonni correction to find which differences among the means are significant. Show calculation of the necessary difference between the means for significance, rank the averages from smallest to largest, and indicate non-significant differences by underlining. Repeat the comparisons above using Fishers LSD and Scheffe\'s method. Indicate any differences in the results
