Practical (simple random sampling)
Practical No 1
Make a vector “name” of names of students in your class. Write a code to draw a sample of 4 students with and without replacement and operate to get the sample.
R codes for practical no 1
Names=c(“Ram”, “Shyam”, ……..)
sample1=sample(Names,2) # sampling without replacement
sample2=sample(students,12, replace=TRUE) # sampling with replacement

Practical No 2
In a population the values of a characteristics Yi, (i=1, 2, 3, 4, 5, 6.), are 6, 7, 3, 4, 8
and 5. Random samples of size two are drawn without replacement. Verify that E
(ȳ) = Ȳand E(s2) = S2. Also calculate V(ȳ).The notations have their usual meaning.
