The American Veterinary Association claims that the annual cost X of medical care for a cat is a random variable with expected value E(X) = $125 and standard deviation SD(X) = $30, and that the annual medical cost Y for a dog has expected value E(Y) = $100 and standard deviation SD(Y) = $25. Assume that medical costs for different dogs and cats are independent. Question 1. How much more in medical costs do you expect to pay for the cat than for the dog?
