Answer:
option (A) 251 phones
Explanation:
Data provided in the question:
Average quantities of prepaid cell phones used = 1500 per week
Standard deviation, s = 145
Lead time for their own brand of prepaid cell phones, L = 3 weeks
lot size = 350 phones
Safety stock = 500 phone
Now,
The standard deviation of demand during lead time will be
= Standard deviation × 
= 145 × √3
= 251.14 ≈ 251 phones
Hence,
The correct answer is option (A) 251 phones

Answer:
Explanation:
GDP is gross domestic product and NDP is net domestic product.
GDP measures market value of total goods and services produced in a particular period of time.
NDP is net domestic product . In its calculation, we deduct the value of depreciation of capital goods produced from the value of GDP.
So
NDP = GDP - depreciation .
So growing gap between GDP and NDP reflects the increasing obsolescence of capital goods , which warrants replacement of capital goods .
OPTION A is correct.
Answer:
a) 39
b) 58
Explanation:
Data provided in the question:
Mean = $70
Standard deviation, s = $8
Number of households, n = 40
Now,
a) number of households whose monthly utility bills are between $54 and $86
z score for $54 = [ 54 - 70 ] ÷ 8 [ z score = [ X - mean ] ÷ s]
or
z score for $54 = -2
z score for $86 = [ 86 - 70 ] ÷ 8 [ z score = [ X - mean ] ÷ s]
or
z score for $54 = 2
Therefore,
P(between $54 and $86) = P(z = 2) - P(z = -2)
= 0.9772498 - 0.0227501
= 0.9544997
Therefore,
number of households whose monthly utility bills are between $54 and $86
= P(between $54 and $86) × n
= 0.9544997 × 40
= 38.18 ≈ 39
b) In a sample of 20 additional house i.e n' = 40 + 20 = 60
thus,
number of households whose monthly utility bills are between $54 and $86
= P(between $54 and $86) × n'
= 0.9544997 × 60
= 57.27 ≈ 58
