Provide an appropriate response.
-A lab orders a shipment of 100 rats a week, 52 weeks a year, from a rat supplier for experiments that the labconducts. Prices for each weekly shipment of rats follow the distribution below: $$\begin{array} { l | c c c } \text { Price } & \$ 10.00 & \$ 12.50 & \$ 15.00 \\\hline \text { Probability } & 0.25 & 0.3 & 0.45\end{array}$$ Suppose the mean cost of the rats turned out to be $13.00 per week. Interpret this value.

A) The average cost for all weekly rat purchases is $13.00.
B) Most of the weeks resulted in rat costs of $13.00.
C) The median cost for the distribution of rat costs is $13.00.
D) The rat cost that occurs more often than any other is $13.00.
