sergejj [24]

Answer:

1/4

Step-by-step explanation:

=> 3/12

=> 1/4

So, 1/4 part remains uncut.

City      Min    Q1   IQR     Q3     Max     Median   Mean    σ    

Rome      0     3.60  8.65  12.25     16         8.25       7.99     5.20

NY           1      2.25  4.69   6.64     20        5.45       6.39     5.91

The box plots below show that both centres are best described by the median.
