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

Answer:
Possible causes of material quantity variance:
1. The use of sub-standard material
2. The use of unskilled labour
3. Wastage of material
Explanation:
Material quantity variance is the difference between standard quantity and actual quantity used multiplied by standard price. The use of sub-standard material reduces the quality of output thereby resulting to unfavorable material quantity variance. The use of unskilled labour also leads to unfavorable material quantity variance. Wastage of material due to low quality of inputs also results to unfavorable material quantity variance.
Answer:
Option (d) is correct.
Explanation:
Suppose Deborah gets a sales bonus at her place of work,
Disposable Income, YD = $ 600
Consumption, C = $480
Savings , S = $ 120
Marginal propensity to consumer, MPC:
= Consumption ÷ Disposable Income
= 480 ÷ 600
= 0.8
Therefore, Deborah marginal propensity to consume (MPC) is 0.80
Option (d)
Answer: (C) Controlling
Explanation:
The controlling is one of the type of management function that helps in managing the various types of organizational function and also it helps in achieve the desirable goals.
It basically take various types of corrective actions for effectively managing the resources and also helps in improving the performance of the company.
