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 = ?
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.
Sorry Ms.Sue, I must have written my answer just as you were posting yours. Your answer, of course, is correct.
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.
To find out how many animals would be expected to have been bought by breeders, we first need to determine the proportion of pet owners who bought their pets from breeders based on the research study.
Given that 3 out of every 20 pet owners bought their pets from breeders, we can express this as a fraction:
3/20
To find the expected number of animals bought by breeders out of the 122 total animals cared for by a vet, we'll multiply this fraction by the total number of animals:
(3/20) * 122
To calculate this, we can simplify the fraction and then perform the multiplication:
3/20 = 0.15 (decimal form)
0.15 * 122 = 18.3
Rounding to the nearest whole number, we would expect approximately 18 animals out of 122 to have been bought by breeders.
