Question details

Problem 2 Use Minitab for this problem The tensile strength of Portland cement is being studied. Several different mixing techniques can be used economically. A completely randomized experiment is conducted to determine if mixing technique has a significant effect on the mean tensile strength of cement. Several measurements of tensile strength are recorded (see table below) for each mixing technique. Tensile Strength (lb/in2) measurements Mixing Technique 1 324 448 364 654 461 467 465 537 4 504 485 422 693 5 398 369 417 538 1 402 600 502 655 4 (a) Use Minitab to perform an ANOVA. Test the hypothesis that mixing techniques affect the mean tensile strength of the cement. Use α = 0.05. Do mixing techniques affect the mean tensile strength of the cement? Yes or No? (b) In Minitab, use a Tukeys test with α = 0.05 to determine which mixing technique(s) maximize the mean tensile strength of Portland cement? Which mixing technique(s) minimize the mean tensile strength of Portland cement?
