In the following designed experiment the bite force of a robot dog is of interest to the manufacturer. The manufacturer wants the bite force to be maximized in order to defend itself (apparently, they are unconcerned with lawsuits from injuries sustained by robo-dog’s bite – kind of dumb, if you ask me). It is suspected that bite force is related to the percentage of carbon fiber in the jaw of robo-dog. Five levels of carbon fiber are used, and five replicates are run in random order, resulting in the data below. Robo-dog Data.xlsx Carbon Fiber Percentage Observations 1 2 3 4 5 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 Analyze the experiment.  Answer the following questions, citing specific Minitab results in your scratch work that support your response to each question.  Simply answering the questions without providing statistical justification in your scratch work will not result in points. 1. Does carbon fiber percentage have an effect on bite force? (yes or no) Use α=0.05 [1] 2. If maximum bite force is desired, which percentage should be selected? Use LSD to justify this answer. [2]

We have studied one-factor DOEs, but not multi-factor DOEs.  What is the main difference between a one-factor and multi-factor DOE?

A movie theater chain has calculated the total rating y for five films. Following parameters were used in the estimation – audience (number of viewers in thousands of people), coefficient based on length of film, critics’’ rating, and coefficient based on personal opinion of movie theater chain owners which will be considered as random error. The results are shown in the table: Movie Rating Data.xlsx Total rating Audience (x1) Length coefficient (x2) Critics rating (x3) 11.55 136.8 8.1 7.9 7.71 116.1 6.2 5.9 13.27 144.2 9.3 8.1 11.79 134.6 7.3 9.4 8.46 121.8 7.0 6.8 The multiple linear regression model for this data is:
