Question

The box plots show the average daily temperatures in January and December for a U.S. city.
What can you tell about the means for these two months?

Answer 1

The mean for December is higher than January's mean.
It is almost certain that January's mean is higher.
There is no way of telling what the means are.
The narrow IQR for January causes its mean to be lower.

Answer 2

I chose A but was wrong so now I am thinking that the narrow IQR for January causes its mean to be lower

Answer 3

I'd be inclined to think its C - no way of telling.

Answer 4

gotta go - best of luck

Answer 5

thank you

Answer 6

to find the mean you add the numbers and then divide.
Its hard to kind of read the numbers but Im assuming that that mean January is around 11.2 and December around 17.
Anyone know if Im doing this wrong?
