A$.$ You are investigating the efficiency of the five machines in your

manufacturing department. How many more units were produced on

average by each machine in shift $1$ than shift $3?$

$11$

$72$

$52$

$82$

$66$

B$.$ You are investigating the efficiency of the five machines in your

manufacturing department. It is accepted within the company that shift $3$

can produce up to $5\%$ less units than shift $1,$ and up to $10\%$ less units than

shift $2$ and remain within acceptable limits$.$ Were these criteria met?

Yes, both criteria were met

No$,$ neither criteria were met

Shift $3$ did not exceed the $5\%$ limit for shift $1,$ but exceeded the $10\%$ limit for shift $2$

Shift $3$ did not exceed the $10\%$ limit for shift $2,$ but exceeded the $5\%$ limited for shift $1$

C$.$ You are investigating the efficiency of the five machines in your

manufacturing department. There are three equal shifts in a $24$ hour period,

and time is lost when the machine is not operating. What machine is the

most efficient when it is operating?

Machine A

Machine B

Machine C

Machine D

Machine E
