An experiment to determine the eect of several methods of preparing cultures for use in commercial yogourt was conducted by a food science research group. Three batches of yogourt were prepared using each of these methods: traditional, ultraltration, and reverse osmosis. A trained expert then tasted each of the nine samples, presented in random order, and judged them on a scale from 1 to 10. A partially complete analysis of variance table of the data is shown below. An incomplete ANOVA Table for the Yogourt Data Sum of Mean Source DF Squares Square Fratio p-value Treatment 17.300 Residual 0.460 Total (a) Calculate the mean square of the treatments and the mean square of the error. (b) Form the Fstatistic by dividing the two mean squares. (c) Find pvalue of this Fstatistic. What does this say about the null hypothesis of equal means? ((1) What assumptions have you made in order to answer part (c)? (e) What is the average size of the error standard deviation in the judge's assessment
