Six different machines are being considered for use in The data in the following table represent the number of hours of manufacturing rubber seals. The machines are being compared relief provided by five different brands of headache tablets with respect to tensile strength of the product. A random sample administered to 25 subjects experiencing fevers of 38- C or more. of four seals from each machine is used to determine whether the Perform the analysis of variance and test the hypothesis at the mean tensile strength varies from machine to machine. The 0.05 level of significance that the mean number of hours of relief following are the tensile-strength measurements in kilograms per provided by the tablets is the same for all five brands. Discuss the square centimeter x 10-1: results.
