Answer: 9 units.
Step-by-step explanation: To calculate the average production units, we need to calculate the sum of all the production units, and divide it by the number of people working in those units:
A=average
PU=production units
A=[tex]\frac{PU1+PU2+PU3+PU4+PU5}{5}[/tex]
[tex]A=\frac{8+11+6+12+8}{5}[/tex]
[tex]A=\frac{45}{5}[/tex]
[tex]A=9[/tex] units
