Consider a sampling distribution with p equals 0.12 and samples of size n each. Using the appropriate​ formulas, find the mean a
Mandarinka [93]
<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= \sqrt{\dfrac{p(1-p)}{n}}

(a) For a random sample of size n equals 5000.

Mean = 0.12

Standard deviation= \sqrt{\dfrac{0.12(1-0.12)}{5000}}

\\\\0.00459565011723\approx0.0046

(b) For a random sample of size n equals 1000.

Mean = 0.12

Standard deviation= \sqrt{\dfrac{0.12(1-0.12)}{1000}}

\\\\=0.0102761860629\approx0.0103

(c) For a random sample of size n equals 500.

Mean = 0.12

Standard deviation= \sqrt{\dfrac{0.12(1-0.12)}{500}}

\\\\=0.0145327216997\approx0.0145
