Question
In Design and Analysis of Experiments, 5th edition (John Wiley & Sons, 2001) D. C. Montgomery describes an experiment in which the tensile strength of a synthetic fiber is of interest to the manufacturer. It is suspected that strength is related to the percentage of cotton in the fiber. Five levels of cotton percentage are used, and five replicates are run in random order, resulting in the data below. Cotton Observations 2 Percentage 15 3. 15 11 9. 20 12 17 12 18 18 25 14 18 18 19 19 30 19 25 22 19 23 35 7 10 11 15 11 After displaying the ANOVA table with the test Ho :all means are equal against Ha: at least two of µi's are unequal. Find the test statistic values and corresponding P-value. What is your conclusion if a = 0.05? O a. f= 14.7568, P-value%=D0, reject Ho b. f = 10.215734,P-value=0.5, do not reject Ho Oc f= 10.215734,P-value%3D0, reject Ho o d. f = 14.7568,P-value=0, do not reject Ho o e f= 1.47568,P-value=D0, reject Ho
