Full solution

Q. Add. Write your answer in simplest form.

\newline

8\sqrt{3} + \sqrt{3}

Combine Like Terms: Combine like terms by adding the coefficients of $\sqrt{3}$ . $8\sqrt{3} + \sqrt{3}$ can be written as $(8 + 1)\sqrt{3}$ because both terms have the same radical part, $\sqrt{3}$ .
Perform Addition: Simplify the expression by performing the addition. $\newline$ $(8 + 1)\sqrt{3} = 9\sqrt{3}$ $\newline$ This is the simplest form since $9$ and $3$ have no common factors that would allow us to simplify the radical further.

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}
