DATA FOR R

[MBA DITU 2013]

Attached is data set:

This is dataset of fuel efficiencies of 38 cars in gallons per mile (GPM). Other variables in data set are weight (in 1000 lb), cubic displacement in cubic inches, number of cylinders, horsepower, acceleration (in seconds from 0 to 60 mph), engine type (V-type and straight (coded as 1)

Perform descriptive analysis on each variable. 

Use appropriate graphical tools to present the data 

Plot relationship of different variables with GPM

Use appropriate analytical method to predict GPM from relevant variables.

Which variable explains most variability in GPM?

Which is next important variable?
