A lab orders 100 rats a week for each of the 52 weeks in the year for experiments that the lab conducts. Suppose the mean cost of rats used in lab experiments turned out to be $13.00 per week. Interpret this value. O A. The median cost for the distribution of rat costs is $13.00. O B. The rat cost that occurs more often than any other is $13.00. OC. Most of the weeks resulted in rat costs of $13.00. O D. The expected or average cost for all weekly rat purchases is $13.00.
