A) 50 households are randomly selected from the town; 14 own a dog
A) The first choice is the most logical because it doesn’t factor in the accommodations that the other two do.
B) There are 14 households that own dogs per 50 houses, so multiply by 7 to find how many dogs are in the whole town:
50 x 7 = 350 houses
14 x 7 = 98 households
