Question

does anyone have basic idea of statistics?

Answer 1

I have this table

Puppy # Weight
1 16
2 46
3 34
4 31
5 21
6 26
7 22
Sum 196

Answer 2

and the question states d) Would it be reasonable to state that this litter contained two “unusual” puppies; i.e., a runt and a giant? Why or why not?

I know my mean is 28, S.D. is 9.27 and my 95% C.I is (9.83, 46.17) but dont know what this question is asking

Answer 3

and also should i use sample S.D. or population S.D.

Answer 4

what i used was population S.D

Answer 5

I think population is the correct one.

Basically, I think the question is asking if you have two outliers in your data. In particular, you have a puppy that weighs 16, and one that weighs 46. Using your S.D. and CI, I think you're supposed to figure out if those puppies are "unusual."

Answer 6

but if it lies in the CI can i say its normal or do i have to do some tests?

Answer 7

I'm honestly not sure. If it lies in the CI though, I would tend to think it's still normal.

But I'm not sure. It's been quite a while since I've had any statistics.

Answer 8

yeah same lol alright ill keep searching on the web :)

Answer 9

Good luck!

Answer 10

Answer 11

Answer 12

Answer 13

like i dont know what that question means. what i wrote is its not reasonable since all those values lie in the confidence intevral so its not unsual i dont know if that is right
