The dataset can be downloaded from https://archive.ics.uci.edu/ml/datasets.html. The dataset contains the fuel consumption of cars in the US measured during 1970-1982. Along with consumption values, there are attribute variables, such as the number of cylinders, displacement, horse power, weight, acceleration, year, origin, and the name of the car:

  • Load the dataset into R using the read.table() function.
  • Produce a box plot of mpg values for each car name.
  • Write a function that will compute the scaled value (subtract the mean and divide by standard deviation) of ...
