The American Veterinary Association claims that the annual cost of medical care for dogs averages $100 with a standard deviation
Taya2010 [7]

Answer:

The probability that the cost for someone's dog is higher than for the cat is 33.2%.

Step-by-step explanation:

With the data given, we know that the difference in cost of medical care of dogs and cats have a normal distribution with μ=-20 and σ=46.

To know the probability of the cost for the dog is higher than the cat, we have to calculate the probability of P(d>0).

Then we have to calculate z, and look up in a standarized normal distribution table.

Calculate z:

z=\frac{X-\mu}{\sigma}=\frac{0-(-20)}{46}=\frac{20}{46}=   0.4348

The probability of the difference being higher than 0, we have:

P(d>0)=P(z>0.4348)=0.33185

We can say that the probability that the cost for someone's dog is higher than for the cat is 33.2%.
