The data file Lubricant.csv (available on Wattle) contains 53 measurements of the viscosity of a particular lubricating agent at various temperatures and pressures. The names of the three variables in the data are viscos, pressure and tempC. At the end of this question, remember to save the related R code as we will be using it again in next tutorial.

Solution

It seems like you forgot to ask a question. However, based on the information you provided, I can guide you on how to load and analyze this data using R.

  1. First, you need to load the data into R. You can use the read.csv function to do this. Make sure the Lubricant.csv file is in your working directory.
lubricant_data <- read.csv("Lubricant.csv")
  1. Now that the data is loaded, you can view the structure of the data using the str function.
str(lubricant_data)
  1. If you want to see the first few rows of the data, you can use the head function.
head(lubricant_data)
  1. To analyze the data, you might want to create some summary statistics. You can use the summary function to get the mean, median, min, max, and quartiles for each variable.
summary(lubricant_data)
  1. You can also create plots to visualize the data. For example, you might want to create a scatter plot of viscosity vs temperature.
plot(lubricant_data$tempC, lubricant_data$viscos, xlab = "Temperature", ylab = "Viscosity")
  1. If you want to save your R code, you can do so by going to File > Save As in your R script editor.

Remember, these are just basic steps. Depending on your specific question or analysis, you might need to do additional steps such as data cleaning, transformation, or advanced statistical modeling.

The article “Wear in Boundary Lubrication” (S. Hsu, R.Munro, and M. Shen, Journal of Engineering Tribology, 2002: 427-441) discuses several experiments involving various lubricants. In one experiment, 45 steel balls lubricated with purified paraffin were subjected to a 40 kg load at 600 rpm for 60 minutes. The average wear, measured by the reduction in diameter, was 673.2 μm, and the standard deviation was 14.9 μm. Assume that the specification for a lubricant is that the mean wear be less than 675 μm. Find the P– value for testingH0 : μ≥675 versus H1 :μ<675. What can we conclude based on the P– value?
