Answer: 1537.

Step-by-step explanation:

Formula for sample size :-

$n=(\dfrac{z_{\alpha/2}\cdot \sigma}{E})^2$

Given : $\sigma=2000$

Margin of error : E= 100

Critical value of 95% confidence : $z_{\alpha/2}=1.96$

Now, the required sample size will be :-

$n=(\dfrac{1.96\cdot 2000}{100})^2\\\\=1536.64\approx1537$

Hence, the minimum sample size required = 1537.
