Full solution

Q. Subtract. Write your answer in simplest form.

\newline

-9\sqrt{3} - 7\sqrt{3}

Identify coefficients: $-9 \sqrt{3} - 7 \sqrt{3}$ $\newline$ Identify the expression that combines the coefficients. $\newline$ $-9 \sqrt{3} - 7 \sqrt{3} = (-9 - 7) \sqrt{3}$
Combine coefficients: Simplify: $(-9 - 7) \sqrt{3}$ $\newline$ $(-9 - 7) \sqrt{3}$ $\newline$ $= -16 \sqrt{3}$

Question

S E=\frac{\sigma}{\sqrt{n}}

\newline

The given equation relates the standard error,

S E

, of a sample mean to the population standard deviation,

\sigma

, and the size of the sample,

n

. Which of the following equations correctly gives the size of the sample in terms of the standard error and the population standard deviation?

\newline

1

\newline

n=\left(\frac{\sigma}{S E}\right)^{2}

\newline

n=\frac{\sigma^{2}}{S E}

\newline

n=\sqrt{\left(\frac{\sigma}{S E}\right)}

\newline

n=\frac{\sqrt{\sigma}}{S E}
