Answer:

a < -12

Step-by-step explanation:

Isolate the variable, a. Treat the < as a equal sign, what you do to one side, you do to the other. Subtract 2 from both sides:

a + 2 < -10

a + 2 (-2) < -10 (-2)

Simplify:

a < -10 - 2

a < -12

a < -12 is your answer.

Answer:

Follows are the solution to this question:

Step-by-step explanation:

$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:

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