does anyone have basic idea of statistics?
I have this table Puppy # Weight 1 16 2 46 3 34 4 31 5 21 6 26 7 22 Sum 196
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
and also should i use sample S.D. or population S.D.
what i used was population S.D
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."
but if it lies in the CI can i say its normal or do i have to do some tests?
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.
yeah same lol alright ill keep searching on the web :)
how may standard deviation away, are the outliers from the mean ?
what do you mean by that ?
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
|dw:1361763918248:dw|
most of the data is within one standard deviation of the mean
so can i say everything is reasonable
or should i argue puppy with weight 16 and 46 are unsual
i reckon those two are unusual
I have another question would you just tell me if i am doing it right
well its on another site if thats okay
i did all my calculations but i know my last question is wrong cuz i got a small n value

im confident a is right, b is 95% right and i know c is wrong lol
i think your are on the right track for b, and im not sure about c , sorry
oo its alright, and I just got one more probability question and thats it for today if you dont mind
http://stats.stackexchange.com/questions/50784/using-the-bayes-theorem i dont know if i got the probabilities wrong from the question but dont know
im sorry i cant be more helpful , maybe post your question here http://openstudy.com/study#/groups/Statistics
you have a puppy that weighs 16, and one that weighs 46. Using your S.D. and CI, I think you're supposed to figuure out if those puppies are unusual.
