Question

Given that I have a population with the following content: [1,2,4,6,2,6,3,7,9]. What command in R programming I should use to:

1) "Visually"(not just data) describe this population?
2) If I take a random sample of size 3 from this population?How to find it proportion of 0's and 1's in this sample?

Thank you in advance!

Answer 1

2

>x=c(1,2,4,6,2,6,3,7,9)

>x

>y=sample(c(0,1),replace=TRUE,length(x))

>y

>z=y[y==0]

>z

>prop=length(z)/(length(x)-length(z))

>prop

this is the program

for exmple

> x=c(1,2,4,6,2,6,3,7,9)

> x

[1] 1 2 4 6 2 6 3 7 9

> y=sample(c(0,1),replace=TRUE,length(x))

> y

[1] 0 1 1 1 0 1 1 0 1

> z=y[y==0]

> z

[1] 0 0 0

> prop=length(z)/(length(x)-length(z))

> prop

[1] 0.5
