Solve the Problem $n , \sum \mathrm { x } _ { i }$

Solve the problem. If necessary, round your answer to one more decimal place than that used for the observations.
-A sample of non-recyclable waste shipping companies in a certain state yielded the following amounts, in tons, of waste shipped during 2005. Determine $n , \sum \mathrm { x } _ { i }$ , and $\bar { x }$ .
$\begin{array}{rrrr}1662 & 480 & 877 & 789 \\852 & 1770 & 592 & 1262 \\421 & 612 & 769 & 826\end{array}$

A)
$\begin{array}{l}\mathrm{n}=12 \\\bar{\sum} \mathrm{x}_{\mathrm{i}}=10,912 \\\overline{\mathrm{x}}=909.3\end{array}$

B)
$\begin{array}{l}\mathrm{n}=12 \\\sum \mathrm{\sum}_{\mathrm{i}}=10,912 \\\overline{\mathrm{x}}=992\end{array}$

C)
$\begin{array}{l}\mathrm{n}=11 \\\sum \mathrm{X}_{\mathrm{i}}=10,912 \\\overline{\mathrm{x}}=992\end{array}$

D)
$\begin{array}{l}n=11 \\\sum x_{1}=10,912 \\\bar{x}=909.3\end{array}$
