Can I have the steps of minitab as well please Question2) An engineer is interested in the effect of cutting speed (A), metal hardness (B), and cutting angle (C) on the life of a cutting tool. Two levels of each factor are chosen, and two replicates of a 2 factorial design are run. The tool life data (in hours) are shown in the following table. (a) Construct the design matrix with effect and all possible interactions Replicate (bManually calculate the...
Solve parts b and d by using SPSS 6.5 An engineer is interested in the effects of cutting speed (A), tool geometry (B), and cutting angle (C) on the life (in hours) of a machine tool. Two levels of each factor are chosen, and three replicates of a 2 factorial design are run. The results are as follows: Replicate Treatment B C Combination 22 31 32 43 35 34 50 55 47 46 44 40 37 36 60 50 54...
Please show calculations using MINITAB PROBLEM 1 A nickel-titanium alloy is. used to make components for jet turbine aircraft engines. Cracking is a potentially serious problem in the final part because it can lead to non-recoverable failure. A test is run at the parts produced to determine the effect of four factors on cracks. The four factors are A pouring temperature Btitanium content C = heat treatment method D amount of grain refiner used Two replicates of a 2 design...
Question 3 A nickel-titanium alloy is used to make aerospace components. Cracking is a potentially serious problem in the final parts because it can lead to failre. An experiment was conducted to determine the effect of three factors on cracks. Three factors at two levels each were selected and two replicates of a completely randomized experiment were run. The factors are Temperature (A), titanium content (B) and heat treatment (C). Treatment Replicate 54 50 42 45 46 43 42 46...
Use the Minitab output to answer the following questions. 1. What is the estimated value of B2? 2. What is the value of SST? 3. What is the value of MSR? 4. What is the value of S2? 5. What is the predicted value of Y when X1 = 7, X2 = 5, and X3 = 3? (round your answer to two decimal places) 6. What is the residual for the predicted value in question 5? The value of Y...

Four factors are thought to possibly influence the taste of a soft-drink beverage: type of sweetener (A), ratio of syrup to water (B), carbonation level (C), and temperature (D). Each factor can be run at two levels, producing a 2 design. At each run in the design, samples of the beverage are given to a test panel consisting of 20 people Each tester assigns a point score from 1 to 10 to the beverage. Total core is the response variable,...
For expert using R , I solve it but i need to figure out what I got is correct or wrong. Thank you # Simple Linear Regression and Polynomial Regression # HW 2 # # Read data from csv file data <- read.csv("C:\data\SweetPotatoFirmness.csv",header=TRUE, sep=",") head(data) str(data) # scatterplot of independent and dependent variables plot(data$pectin,data$firmness,xlab="Pectin, %",ylab="Firmness") par(mfrow = c(2, 2)) # Split the plotting panel into a 2 x 2 grid model <- lm(firmness ~ pectin , data=data) summary(model) anova(model) plot(model)...
Calculation Practice Compute the answers to Questions 4 - 6 without the use of statistical software. Be sure to supply all the intermediate information asked for by the question. To aid you, SS has been supplied. All three calculation practice questions will make use of the following dataset: Participant Factor A Lvll Factor A Lvl 2 Factor A Lvl 3 Factor B Lvl 1 Factor B Lvl 2 14 5. For this problem continue to ignore the levels of Factor....
Aa Aa 11. Two-factor ANOVA Emphasis on calculations W.Thomas Boyce, a professor and pediatrician at the University of British Columbia, Vancouver, has studied interactions between individual differences in physiology and differences in experience in determining health and well-being. Dr. Boyce found that some children are more sensitive to their environments. They do exceptionally wel when the environment is suppo「tive but are much more likely to have mental and physical health problems when the environment has challenges. You decide to do...
