Answer: Pigs

Step-by-step explanation:

For each animal type, divide the number who caught the disease over the total number of that particular animal.

  • Cows: 3/53 = 0.057 = 5.7% approximately
  • Pigs: 4/75 = 0.53 = 5.3% approximately
  • Chickens: 2/30 = 0.067 = 6.7% approximately

Unfortunately the cows and chickens have percentages higher than 5.5%, so they are not healthier compared to the average.

Pigs on the other hand have a percentage less than 5.5%, so they seem to be slightly healthier than the county average.
