The average score of the student in the class at a 99% confidence lies between 1.252 and 3.028
Explanation:
Given values are
n = 14 = 2.14 σ = 1.29 z value for 99% confidence = 2.576
The mean is known one
= (z σ/√14)
= (2.576 ×1.29÷√14)
= 2.576 × 0.345
= 0.888
= mean- 0.888 = 2.14 - 0.888 = 1.252
= mean+0.888 = 2.14 + 0.888 = 3.028
The average score of the students in the class at a 99% confidence lies between 1.252 and 3.028

Answer:
Explanation:
Reorder point quantity is the level at which an inventory is expected to be restocked , calculated by finding the sum of demand over the lead time and the safety stock days
Daily usage = 800 feet / day
Lead time = 6 days
Desired service level = 95%
Risk level = 1-0.95 =0.05
safety stock at 0.05 = 1800
Reorder point = expected demand in (LT) + safety stock
= (800*6) + 1800
= 4800+1800 = 6600 feet.
