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
