<h2>Answer with explanation:</h2>
Consider a sampling distribution with p equals 0.12 and samples of size n each.
Then, formula for mean = p
Formula for standard deviation=
(a) For a random sample of size n equals 5000.
Mean = 0.12
Standard deviation=
(b) For a random sample of size n equals 1000.
Mean = 0.12
Standard deviation=
(c) For a random sample of size n equals 500.
Mean = 0.12
Standard deviation=
Answer:
As the model is shown below.
As per model a thing is divided into five parts.There are three things and each one of them is being divided into five equal parts.
The value of fifth part of each of them is 1/5.
If we consider each part of a thing as one,
So, total number of parts = 15
Total thing=3
So, the answer of the above model is 3÷ 15.
Out of all the options which are 15÷15 , 3÷115 , 3÷15, 15÷15 →3÷15 is correct.
