Population of dogs mean rate 26 pounds and a deviation of 3.6 pounds, Population of cats mean rate 10.5 and a deviation of 1.9 if a dog weights 24 pounds and a cat weights 19 pounds. which weighs more for its population?
Z = (score-mean)/SD
Which has the highest value?
However, you don't need to go through this, because (assuming no typos) one value is above the mean and the other is below.
