Suppose a simple random sample of size n = 1000 is obtained from a population whose size is N = 2,000,000 and whose population p

faltersainse [42]

Answer:

$p(x\geq 520) = 0.0293$

Step-by-step explanation:

Given data:

random sample size n = 1000

Population size is N - 2,000,000

P = 0.49

We know

$\sigma_p = \sqrt{\frac{p*(1-p)}{n}}$

$\sigma_ p = \sqrt{\frac{0.49*(1-0.49)}{1000}} = 0.0158$

Probability for having X =520

sample proportion $\hat p = \frac{520}{1000} = 0.52$

$p(x\geq 520) = P(\hat p\geq)$

$= P(Z\geq \frac{0.52 - 0.49}{0.0158})$

$= P(Z\geq 1.89) = 0.0293$

$p(x\geq 520) = 0.0293$
