95 \% \ the confidence level for z:

\alpha = 1 - 95 \% \\\\

   = 1 - 0.95 \\\\        = 0.05

\to \frac{\alpha}{2} = \frac{0.05}{2} = 0.025\\\\\\to Z \  \frac{\alpha}{2} = Z_{0.025} = 1.96

Calculating the Margin of error:

E =   Z\  \frac{\alpha}{2}  \times ( \frac{\sigma}{\sqrt{n}})

   = 1.96 \times ( \frac{5000}{\sqrt{\sqrt{100}}})\\\\= 980

The population means estimate a 95 % confidence interval is:

\to \bar{x} \frac{+}{-} E\\\\ = \$ 90000 \frac{+}{-} 980
