Explanation / Answer

R CODE :

> dash_time= c(9.80,9.80,10.08,10.09,10.11,10.13)
> no_of_children=c(0,1,1,1,2,2,2,2,2,2,2,4,5)
> no_of_cars=c(0,1,1,3,3,4,5,5)
> mean1= mean (dash_time)
> mean1
[1] 10.00167
> mean2=mean(no_of_children)
> mean2
[1] 2
> mean3=mean(no_of_cars)
> mean3
[1] 2.75
> median1=median(dash_time)
> medin1
Error: object 'medin1' not found
> median1
[1] 10.085
> median2=median(no_of_children)
> median2
[1] 2
> median3=median(no_of_cars_
+ median3=median(no_of_cars)
Error: unexpected symbol in:
"median3=median(no_of_cars_
median3"
> median3=median(no_of_cars)
> median3
[1] 3
