please explain also.
A research study shows that 3 out of every 20 pet owners bought their pets from breeders. Of the 122 animals cared for by a vet, how many would you expect to have been bought by breeders?
Multiply: 3/20 * 122 = ?
Sorry Ms.Sue, I must have written my answer just as you were posting yours. Your answer, of course, is correct.
As far as I am concerned it could be all 122, none,or any number inbetween. As I understand it, statistics are generalizations and do not apply to specific examples. But, of course, I could be wrong.
Since there is a discussion going on about this problem, I'll weigh my opinion in, too. In the spirit of what I PRESUME the problem to be, Ms Sue is correct. In the spirit of generalizations, E.G. is correct, too. However, technically, I think the problem is not solvable BECAUSE, the statement is that "3 out of every 20 pet owners bought their pets FROM breeders" but the question is "how many would you expect to have been bought BY breeders.":)
Good point, DrBob. I didn't read the question carefully. As it stands, there is no answer.
