A lab orders a shipment of 100 rats a week, 52 weeks a year, from a rat supplier for experiments that the lab conducts. Prices for each weekly shipment of rats follow the distribution below:
Suppose the mean cost of the rats turned out to be $13.38 per week. Interpret this value.
▸ Most of the weeks resulted in rat costs of $13.38.
▸ The rat cost that occurs more often than any other is $13.38.
▸ The average cost for all weekly rat purchases is $13.38.
▸ The median cost for the distribution of rat costs is $13.38.
