Cattle are classified according to age (young, medium, and old) and carcass quality (grades A, B, and C). In one study, the animals were classified as :
$\begin{array}{lccccl}
& \text { Grade A } & 75 & \text { medium } & \text { old } & \text { Total } \
& \text { Grade B } & 100 & 80 & 25 & 180 \
& \text { Grade C } & 75 & 20 & 30 & 150 \
\text { Total } & 250 & 50 & 45 & 170 \
& & 150 & 100 & 500
\end{array}$
The chi-square statistic for testing if there is an association between age and carcass quality was calculated. What is the expected frequency for the $( 2,2 )$ cell?
A) 26
B) 45
C) 60
D) 90
