question 11

Multiple Choice

A teacher figures that final grades in the chemistry department are distributed as: $\mathrm { A } , 25 \% ; \mathrm { B } , 25 \% ; \mathrm { C } , 40 \%$ ; D, $5 \% ; F , 5 \%$ . At the end of a randomly selected semester, the following number of grades were recorded.

$\begin{array}{l|ccccc}\text { Grade } & \text { A } & \text { B } & \text { C } & \text { D } & \text { F } \\\hline \text { Number } & 36 & 42 & 60 & 8 & 14\end{array}$

• A) \(5.25\)
