Answer:
lower range 33.822 years
upper range 38.178 years
Explanation:
step 1:
48 -1 = 47
step 2:
(1 - 95%) / 2 = 0.025
step 3:
we look at the T distribution table for degrees of freedom (df) = 47, and α = 0.025; = 2.0117
step 4:
divide sample standard deviation by square root of sample size
7.5 years / √48 = 7.5 / 6.9282 = 1.0825
step 5:
multiply results from step 3 and 4
2.0117 x 1.0825 = 2.178
step 6:
for the lower range, subtract step 5 from sample mean
36 - 2.178 = 33.822
step 7: for the upper range, add step 5 with sample mean
36 + 2.178 = 38.178

Answer:
Correct Answer is (B)
Explanation:
We look at the objectives the government has in mind to achieve;
- stability in international trade
- stability in investment
Which of the listed policies will achieve these goals?
- the tool here used to control international trade is foreign exchange trading
- the tool used to control investment is interest rate
To achieve stability in these 2 indicators, both tools should be controlled. Thus the monetary policy & exchange rate regime to choose here is:
Controlling the interest rate in the country and imposing restrictions on foreign exchange trading.
Option (C) won't suffice because an independent monetary policy is necessary.
Answer:
Order size = 200 units
Number of order = 5 times
Explanation:
<em>The number of order per year will be equal to the Annual demand divided by the EOQ.</em>
<em>No of orders = Annual Demand / EOQ</em>
Economic order quantity (EOQ)
The Economic Order Quantity (EOQ) is the order size that minimizes the balance of ordering cost and holding cost. At the EOQ, the carrying cost is equal to the holding cost.
It is computed using he formulae below
EOQ = √(2× Co× D)/Ch
Ch- Carrying cost per unit per annum- $1
Co- Ordering cost per order -20
EOQ =√(2× 20× 1000)/1
= 200 units
Order size = 200 units
Number of order = 1000/200 = 5 times
