Two Companies, a and B, Package and Market a Chemical $\quad$

Two companies, A and B, package and market a chemical substance and claim 0.15 of the total weight of thesubstance is sodium. However, a careful survey of 4,000 packages (half from each company) indicates that theproportion varies around 0.15, with the results shown below. Find the percentage of all chemical B packagesthat contain a sodium total weight proportion above 0.150. $\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\text { Proportion of Sodium }$
$\begin{array}{cccccc}\hline & <0.100 & 0.100-0.149 & 0.150-0.199 & >0.200 \\\hline & \text { A } & 25 \% & 10 \% & 10 \% & 5 \% \\{\text { Chemcal Brand }}\\& \text { B } & 5 \% & 5 \% & 10 \% & 30 \%\end{array}$

A) 80%
B) 40%
C) 50%
D) 55%
