Explanation / Answer

##R code to calculate covarience

##store car numbers in car dataframe
##put car numbers in a sequence
car<-seq(1:9)

##Store car numbers and mpg
engine_size<-c(2.5,2.0,2.5,3.3,3.1,2.3,2.5,2.1,3.2)
mpg<-c(31,29,28,22,21,31,24,25,21)

##Calculate covarience and round covarience to two decimal places
covarience<-round(cov(engine_size,mpg),2)

##print covarience
covarience
