Answer with explanation:

1.Mean of a Data set

   [tex]=\frac{\text{Sum of all the observation}}{\text{total number of observation}}[/tex]

[tex]=\frac{10+9+11+8+10+12+2+7+8+0+12+10+8+11+3+12+6+7+4+3}{20}\\\\=\frac{153}{20}\\\\=7.65[/tex]

2. Range = Maximum value in two conferences - Minimum value in two conference

= 12 - 0

=12

The mean number of wins for teams from the two conferences is 7.65.

The range in wins is  12.
