OpenStudy (lizz123):

OpenStudy (anonymous):

Woah that was a quick response!

OpenStudy (lizz123):

ikr

OpenStudy (anonymous):

When the outliers are removed, how does the mean change? Answer choices: The mean remains the same. The mean decreases by 2. The mean increases by 2. There are no outliers.

OpenStudy (godlovesme):

lol ^^^ :P

OpenStudy (godlovesme):

@ImaGuest help ?

OpenStudy (agl202):

I think its A.

OpenStudy (anonymous):

Sorry, I had to do something right after I posted the question. Agl what makes you think it's A?

OpenStudy (godlovesme):

@Agl202 direct answers are against the law -.- please explain thanks!

OpenStudy (agl202):

sorry! :(

OpenStudy (lizz123):

I think it is B. Here is way

OpenStudy (lizz123):

If you add all the numbers 15+23+24+26+27+35 what does that equal @ImaGuest

OpenStudy (anonymous):

150

OpenStudy (lizz123):

Now divide that by how many numbers their are

OpenStudy (godlovesme):

it's fine :) @Agl202 just to make sure the person understands :)

OpenStudy (lizz123):

So theres 6. So What is\[150\div6\]

OpenStudy (anonymous):

25

OpenStudy (lizz123):

yeah.

OpenStudy (lizz123):

Now if you remove 15 since it is the least one. You now add 23+24+26+27+35. What does that equal

OpenStudy (anonymous):

Wait, so add those numbers to 25, or start over and add them again but without the 15?

OpenStudy (lizz123):

Yeah add them again without 15.

OpenStudy (anonymous):

Okay

OpenStudy (anonymous):

135

OpenStudy (anonymous):

Could've just subtracted 150 by 15 but I took the long way :/

OpenStudy (lizz123):

Yes, now you have to divide 135 by the number there is.

OpenStudy (anonymous):

Okay

OpenStudy (lizz123):

But without counting 15

OpenStudy (anonymous):

25

OpenStudy (anonymous):

Sorry 27

OpenStudy (lizz123):

Yes, 27 is your answer. So, when you added witth 15 you got the answer of 25. Now without 15 you got 27.

OpenStudy (lizz123):

What do you think the answer is

OpenStudy (lizz123):

I actually made a mistake I think the answer is C. The mean increases by 2. We did the steps together you should understand

OpenStudy (lizz123):

@ImaGuest

OpenStudy (anonymous):

Sorry, I was sneezing non stop. Yeah, I thought the answer was C too. I was gonna ask why do you think it's B and not C. But you corrected yourself so..... Anyways, thank you so much for helping me!

OpenStudy (lizz123):

no prob. Glad to help

OpenStudy (anonymous):

Do you think you could help me with one more question? I can tag you in another question and give you another medal?

OpenStudy (lizz123):

OpenStudy (lizz123):
