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!
Answer:
Production for the third quarter 159,500
Explanation:
Sales for the period 161,000
Desired ending inventory 4,600
Total production needs 165,600
Beginning Inventory (6,100)
Production for the third quarter 159,500
The sales for the period and the desired ending inventory are the total units we need for the quarted.
the beginning inventory reduces the production because are units we already have

Answer:
The answer is $13,558
Explanation:
βP = 1.0 = 1.48A+ [.72 × (1-A)]
A = .368421
Investment in Stock A = $36,800 × .368421 = $13,558
