A laboratory engineer 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: Observations ... Cotton (%) 1 2 3 4 15 7 7 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 Does cotton percentage affect breaking strength? Test the hypothesis at alpha 0.05 F critical is Blank 1 F stat is Blank 2 Decision is to Blank 3 the null hypothesis. (accept or reject) Blank 1 Add your answer Blank 2 Add your answer Blank 3 Add your answer
