Based on the sampling done, the control limits for 3-sigma x
overbarx chart are (round all intermediate calculations to three
decimal places before proceeding with furthercalculations):
Upper Control Limit (UCL Subscript x overbarUCLx) = ?
Lower Control Limit (LCL Subscript x overbarLCLx) = ?
Based on the x overbarx-chart, the wire cutting process has
been
IN CONTROL or OUT OF CONTROL?
The control limits for the 3-sigma R-chart are (round all
intermediate calculations to three decimal places before proceeding
with further calculations):
Upper Control Limit (UCL Subscript Upper RUCLR) = ?
Lower Control Limit (LCL Subscript Upper RLCLR) = ?
Based on the R-chart, the wire cutting process has been
IN CONTROL or OUT OF CONTROL ?

A small firm intends to increase the capacity of a bottleneck
operation by adding a new machine. Two alternatives, A and B, have
been identified, and the associated costs and revenues have been
estimated. Annual fixed costs would be $36,000 for A and $31,000
for B; variable costs per unit would be $7 for A and $11 for B; and
revenue per unit would be $18.
a. Determine each alternative’s break-even point
in units. (Round your answer to the nearest whole
amount.)
QBEP,A | units |

b. At what volume of output would the two
alternatives yield the same profit (or loss)? (Round your
answer to the nearest whole
