Objective(s) of this Assignment:

The assignment is being uploaded to build up the concepts of modern tools of survey sampling and R codding.

Assignment No.1 (Lessons 10-18)

Question 1: Marks 3+4+3 =10

Find n_1, , and by proportional allocation from the following information.

=1580, =1140, =125, =114 and =440.

Explain the condition when (population following the linear trend).

Prove that for unequal cluster size.

Question 2: Marks 5+5=10

Prove that the variance of the sample mean by systematic sampling is:

`Write simulated R coding program for generating 1000 samples of size 6 from systematic sampling by using following information. Also find the mean of each sample and the mean of means. 120,140,225,332,221,224,228,55,91,741,852,963,159,852,369,147,236,256,289,123,456,789,258,369,147,987,654,321,193,367,581,111,222,333,444,555,666`
