Marin Company produces two software products (Cloud-X and Cloud-Y) in two separate departments (A and B). These products are hig
hly regarded network maintenance programs. Cloud-X is used for small networks and Cloud-Y is used for large networks. Marin is known for the quality of its products and its ability to meet dates promised for software upgrades. Department A produces Cloud-X, and department B produces Cloud-Y. The production departments are supported by two support departments, systems design and programming services. The sources and uses of the support department time are summarized as follows:_______.
To Total
Department Department Labor
From Design Programming A B Hours
Design - 5,000 1,000 9,000 15,000
Programming 400 - 600 1,000 2,000
The costs in the two service departments are as follows:_______.
Design Programming
Labor and materials (all variable) $ 50,000 $ 36,000
Depreciation and other fixed costs 40,000 4,000
Total $ 90,000 $ 40,000
Required:1. Determine the total support costs allocated to each of the producing departments using (a) the direct method, (b) the step method (design department goes first), and (c) the reciprocal method? (Do not round intermediate calculations. Round your final answer to nearest whole dollar amount.)2. The company is considering outsourcing programming services to DDB Services Inc. for $52.00 per hour. Should Marin do this?Note: there's 2 requirements , please make sure you do both with explaination :)

Answer:
Control limits for x_bar are between 59.076 and 60.924
Control limits for R are between 0.669 and 5.331
Explanation:
Given data:
x_bar = 60 mph
n = 10
R = 3 mph
Step 1: Factors (see table attached)
At n = 10, factors for computing control charts limits are,
A2 = Mean factor = 0.308
D3 = Lower range = 0.223
D4 = Upper range = 1.777
Step 2: Control limits for x_bar
Lower Control limit:
LCL = x_bar - A2*R = 60 - (0.308)(3) = 60 - 0.924 = 59.076
Upper Control limit:
UCL = x-bar + A2*R = 60 + (0.308)(3) = 60 + 0.924 = 60.924
The control limits for x_bar are between 59.076 and 60.924
Step 3: Control limits for R
Lower Control limit:
LCL = D3*R = 0.223(3) = 0.669
Upper Control limit:
UCL = D4*R = 1.777(3) = 5.331
The control limits for R are between 0.669 and 5.331
Hope this helps!
