The standard deviation of sample equals: 11
Explanation:
Given:
variance of sample () = 121
no, of observations made = 441
standard deviation = ?
By using the formula:
Standard deviation (S) =
=
=
= 11
Hence the standard deviation is equal to 11.
Answer:
The computations are shown below:
Explanation:
a. The computation of the economic order quantity is shown below:
= 229 units
The carrying cost is come from
= $2.40 × 20%
b. Time between placement of orders is
= Economic order quantity ÷Annual demand
= 229 ÷ 280
= 0.8179 years
So,
= 0.8179 × 365 days
= 298.53 days
We assume 365 days in a year
c. The average annual cost of ordering cost and carrying cost equals to
= Holding cost + ordering cost
= (Economic order quantity ÷ 2 × Holding cost) + (Annual demand ÷ Economic order quantity × ordering cost)
= (229 units ÷ 2 × $0.48) + (280 ÷ 229 units × $45)
= $54.96 + $55.02
= $109.98
d) Now the reorder level is
= Demand × lead time + safety stock
where, Demand equal to
= Expected demand ÷ total number of weeks in a year
= 280 pounds ÷ 52 weeks
= 5.38461
So, the reorder point would be
= 5.38461 × 3 + $0
= 16.15 pounds
