Six Sigma Black Belt Session 10 Correctly Answered Questions| UpToDate | Already Graded A+

The next several questions are based on analysis of the dataset download provided on the course page where you launched the quiz module. The data are from a 2-level full factorial experiment with 2 replicates to evaluate the effect of three factors, A, B and C on the life of a product. Analyze the data and use your conclusions to answer the next few questions. Which main and interaction effects have a significant impact on the life of the product? Use a 5% significance level to make your decision. A) C, AC, BC B) B, C, BC C) B, C, AC D) A, B, C, AB E) A, C, AC : C) B, C, AC Which of the following is true of the effects identified as significant in the previous question? A) B, C and AC have a positive effect on Life. 2 | P a g e B) B and C have a negative effect while AC has a positive effect on Life. C) B, C and AC have a negative effect on Life. D) AC has a negative effect while B and C have a positive effect on Life. E) It is impossible to tell the direction of the effect. : D) AC has a negative effect while B and C have a positive effect on Life. The final (reduced) model consists of the significant factors and any main effects to preserve hierarchy. What is the final model equation for the factor effects in coded units? A) 17.47 + 0.81*A + 4.19*B + 3.56*C - 0.44*AB - 6.06*AC - 1.19*BC - 1.81*ABC B) 28.64 + 0.67*A + 3.43*B + 2.92*C - 4.97*AC C) 28.28 + 0.66*A + 3.39*B + 2.88*C - 4.91*AC D) 17.47 + 0.41*A + 2.09*B + 1.78*C - 3.03*AC E) 17.47 + 0.41*A + 2.09*B + 1.78*C - 0.22*AB - 3.03*AB - 0.59*BC - 0.91*ABC : D) 17.47 + 0.41*A + 2.09*B + 1.78*C - 3.03*AC Examine the cube plot for factors A, B and C. Which combination of the three factors maximizes the life of the product? A) A = High, B = Low, C = High B) A = High, B = Low, C = Low C) A = Low, B = Low, C = High D) A = High, B = High, C = Low E) A = Low, B = High, C = High 3 | P a g e : E) A = Low, B = High, C = High Once again examine the cube plot for factors A, B and C. What combination of the three factors produces the second highest value for the life of the product? A) A = High, B = Low, C = High B) A = High, B = High, C = Low C) A = Low, B = Low, C = High D) A = Low, B = High, C = High E) A = High, B = Low, C = Low : B) A = High, B = High, C = Lo
