For the following question answer all the parts in R studio use R language. mpg dataset is the default dataset in R studio. 1. Load the built-in “mpg” dataset in RStudio using data(mpg) and write code to perform the following: (a) Obtain the summary statistics for the “hwy” variable (Highway MPG). (b) Create a box plot of the “cty” variable (City MPG). (c) Create a scatterplot of the “hwy” variable against the “cty” variable. What kind of relationship do the two variables have?
