PolarNik [594]

Answer Z=2
The math …..
Multiple ( ) first
15z -21 -18z +22 = 32z - 52 -17
Combine like terms
-3z + 1 = 32z -69
Move like terms to isolate Z
-35z = -70 two negative make positive
35z = 70
Divide both sides by 35 to isolate Z
Z = 2

The Eks Survey Company employs 2000 people to conduct telephone surveys. Because many people don't like to answer such surveys,

Kobotan [32]

Use the next formula to find the margin or error:

$MOE=z*\frac{\sigma}{\sqrt{n}}$

z is the critical value (For a 95% confidence level the z-score is 1.95998)

σ is the standard deviation

n is the sample size

$\begin{gathered} MOE=1.95998*\frac{20.4}{\sqrt{36}} \\ \\ MOE\approx6.6639 \end{gathered}$ <h2>Then the margin of error is: 6.6639</h2> $\begin{gathered} \bar{x}\pm MOE \\ \\ 38.6\pm6.6639 \end{gathered}$
