Question

I've been stuck on part e. for a while. I already asked this question, but I'm really not sure. Please check my answer for e.
__________________________________________________________
A sports store sells ski wax. Here are the numbers of ski wax tubes sold each day for a week:
5, 7, 6, 5, 17, 5, 4
a. outlier: 17
b. mean with outlier: 7
c. mean without outlier: 5
d. how does including the outlier affect the mean?: It increases the mean.
e. Should the outlier be used to report the mean number of ski wax tubes sold in a week?: I think no, because the outlier makes the mean less reflective of the true average since it increases the mean.
____________________________________________________________
Is part e. correct?

Answer 1

*Also, in part e. it is also supposed to say "Explain why". I had to type this out myself since my math course is on paper. Sorry for any mistakes.

Answer 2

Depends. If the 17 were sold on a day, like maybe Friday before the weekend ski races, when your wax sales go up every week in the spring then the mean including the outlier would be more meaningful than the squished average. If the first number is for Monday, then that 17 is on Friday.

Answer 3

That's Damon's response that you copied and pasted from my other post. Why did you do that? Not very helpful at all.

Answer 4

I thought that looked kind of familiar !

Answer 5

Well, anyhow it's too late, since I submitted my assignment. I hope my answer is correct...

Answer 6

Aww... I got it wrong. I WAS supposed to include the outlier! :(
I don't really understand why.

Answer 7

i like to plagiarize things

Answer 8

Tell it to the judge. Good luck in court!
