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

$\\\\=0.0145327216997\approx0.0145$

Jlenok [28]

Answer:

The answer is 9x² + 3x - 2.

Step-by-step explanation:

1) Collect like terms.

$(7x^{2} + {2x}^{2} ) + ( - 2x + 5x) + (8 - 10)$

2) Simplify.

${9x}^{2} + 3x - 2$

Therefor, the answer is 9x² + 3x - 2.
