Full solution

Q. Add. Write your answer in simplest form.

\newline

-5\sqrt{3} + 7\sqrt{3}

Combine like terms: Combine the like terms $-5 \sqrt{3}$ and $7 \sqrt{3}$ . $\newline$ Identify the like terms which are both terms with $\sqrt{3}$ . $\newline$ $-5 \sqrt{3} + 7 \sqrt{3} = (-5 + 7) \sqrt{3}$
Simplify expression: Simplify the expression $(-5 + 7) \sqrt{3}$ . $\newline$ Calculate the sum of the coefficients $-5$ and $7$ . $\newline$ $(-5 + 7) \sqrt{3} = 2 \sqrt{3}$

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}
