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 :/

Yes, now you have to divide 135 by the number there is.
OpenStudy (anonymous):

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!
