Statapult Our goal with this project is to test 4 different factors regarding the distance a ball was thrown via catapult.(Shown above) During the course of this project, all of the various labeled setting you can see (Bungee Position, Pin Elevation, and Angle of Throw) were tested in a series of ANOVA tests to find which factor affected the di...

A rocket propellant manufacturer is studying the burning rate of propellant from three production processes. Four batches of propellant are randomly selected from the output of each process, and three determinations of burning rate are made on each batch. The results follow. State the model equation and hypotheses to be tested. Perform the analys...

library(FrF2) 8.2 Suppose that in Problem 6.15, only a one-half fraction of the 24 design could be run. Construct the design and perform the analysis, using the data from replicate I. 6.15. 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 i...

6.8. A bacteriologist is interested in the effects of two different culture media and two different times on the growth of a particular virus. He or she performs six replicates of a 22 design, making the runs in random order. Analyze the bacterial growth data that follow and draw appropriate conclusions. Analyze the residuals and comment on the m...

In a process development study on yield, four factors were studied, each at two levels: time (A), concentration (B), pressure (C), and temperature (D). A <- rep(c(-1,1),8) B <- rep(c(-1,-1,1,1),4) C <- rep(c(rep(-1,4),rep(1,4)),2) D <- rep(c(rep(-1,8),rep(1,8))) results <- c(12, 18, 13, 16, 17, 15, 20, 15, 10, 25, 13, 24, 19, 21, 17, 23) ...

Perform a designed experiment to determine the effect of Pin Elevation and Release Angle on distance in which a red ball is thrown when the Bungee Position is fixed at the second position. Settings one and three of Pin Elevation should be investigated as a fixed effect, as well as settings of the Release Angle corresponding to 110, 140, and 170 d...

1. An article in Quality Progress (May 2011, pp. 42–48) describes the use of factorial experiments to improve a silver powder production process. This product is used in conductive pastes to manufacture a wide variety of products ranging from silicon wafers to elastic membrane switches. We consider powder density (g/cm2)(g/cm2) as the response...

5.3. The yield of a chemical process is being studied. The two most important variables are thought to be the pressure and the temperature. Three levels of each factor are selected,and a factorial experiment with two replicates is performed. The yield data are as follows: temp150 <- c(90.4, 90.7, 90.2 ,90.2, 90.6, 90.4) temp160 <- c(90.1, 90.5,...

3.23. The effective life of insulating fluids at an accelerated load of 35 kV is being studied. Test data have been obtained for four types of fluids. The results from a completely randomized experiment were as follows: type1 <- c(17.6 ,18.9, 16.3 ,17.4, 20.1, 21.6) type2 <- c(16.9, 15.3 ,18.6, 17.1, 19.5, 20.3) type3 <- c(21.4, 23.6 ,19.4, 18....
