Please use R. Thank you!

Q4: (1) Create vector s as a random sample of 12 numbers from 1, 2, 3, ..., 99, 100 without replacement, using function sample. (2) Print the data structure of s.

Answer 1

SOURCE CODE:

*Please follow the comments to better understand the code.

**Please look at the Screenshot below and use this code to copy-paste.

***The code in the below screenshot is neatly indented for better understanding.

# STEP1 Create the vector s as the random sample from 1 to 100

#Pick 12 random numbers. So, size=12

#Without Replacement, So, replace=FALSE

s <- sample(x = 1:100,size = 12,replace = FALSE)

#STEP 2

# Print the data structure of s

print(s)

===================================================

WE WILL GET 12 RADNOM UNIQUE numbers from 1 to 100 every time we run the program

=====================================================
