A lab in Michigan State University 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 $15.00 per week. Interpret this value.

a.Most of the weeks resulted in rat costs of $15.00

b.The median cost for the distribution of rat costs is $15.00

c.The expected or average costs for all weekly rat purchases is $15.00

d.The rat cost that occurs more often than any other is $15.00
