Answer:

The correct answer is "1668". A further solution is provided below.

Step-by-step explanation:

According to the question,

Estimated proportion,

$\hat{p} = \frac{574}{1007}$

$=0.57$

Margin of error,

E = 0.02

Level of confidence,

= 90%

= 0.90

Critical value,

$Z_{0.10}=1.65$

Now,

⇒ $0.02=1.65\times \sqrt{\frac{0.57\times 0.43}{n} }$

$0.0004=2.7225\times \frac{0.2451}{n}$

$n=\frac{2.7225\times 0.2451}{0.0004}$

$=1668.21$

or,

$n \simeq 1668$
