Help, please. 

 

The double bar graph shows the monthly snowfall amounts (in inches) for two cities over a six-month period. Compare the mean monthly snowfall amounts of the two cities for these months. (Round your answers to two decimal places.)

 

 

 

The mean of City 1 was = __________ and the mean of City 2 was = _________. Therefore, City 1 had a  greater mean monthly snowfall amount than City 2.

I'll start you out....you can finish it, I'm sure....

City 1 :

Month 1 =12

Month 2 = 18

           3 = 21  (I think)

           4 = 16

           5 = 10

Month 6 =  6         Add these numbers and divide by 6 to get the mean

     12 + 18 + 21 + 16 + 10 + 6    = 83      83/6 = 13  5/6   inches = mean

 

 

Now do this for City 2    and compare......

Ugh, I have to read from the table. Well, whatever, I'll try. For, City 2, we have \(7+17+20+19+7+2=72.\) And, the mean is just \(\frac{72}{6}=\boxed{12}.\)
