Answer:
Explanation:
Experiments were performed for 240 people, 60 people test positive.
Step 1: we calculate the sample proportion; p= 60/240= 0.25.
Step 2: calculate the standard error for the sample, which is the square root of sample proportion,p = p(1-p)/n, n=100
0.25(1-0.25)/100
= 0.04.
Step 3: calculate the test statistics; assuming the hypothesis test percentage is 25%
Then, we say 0.25-1=0.75
-0.75/0.04
= -1.875.
In particular, the sample results are -1.875 standard error.
Probability of Z is less than -1.875.
Look up it value in the Z table
Answer:
33.33%
Explanation:
Unemployment rate is the proportion of the labour force without a job
Unemployment rate = (number of unemployed workers / total labour force ) x 100
25 /75 x 100 = 33.33%
Answer:
correct option is c. $27,000
Explanation:
given data
hold as reserve = 9 %
excess reserves = $18,000
sells bill = $9,000
solution
we know that here if bank sells off treasury bill to the Fed
it is getting amount in return
so that money complete lent out in the form of loan
so here total amount that bank lent out is express as
total amount that bank lent out = $18000 + $9000 ......................1
total amount that bank lent out = $27000
so correct option is c. $27,000
Answer: B. Capitalized in the machine account
Explanation:
To capitalized an equipment or asset in this case a machine, is to put the equipment on the balance sheet of expensing. When a piece of equipment is bought for $500 , rather than to report it as a $500 expense immediately, it will be listed in the balance sheet as a $500 asset.
The machine in this case the machine increased it production capacity by 25% without expanding its useful life, the cost of improvement is " capitalized in the machine account ".
Answer:
D. rightward shift of the production possibilities curve.
Explanation:
Production possibility curve shows all the two combinations of goods that can be produced in an economy given its resources and technology.
Shift of the possibility possibility curve to the right shows that technological progress has occurred. This shows economic growth.
When production is taking place at a point within the curve, production is inefficient. A point outside the production possibilities curve is unattainable. Movement from a point inside to a point outside the production possibilities curve shows that the economy is moving from inefficency to an unattainable production point.
Movement from a point near the vertical axis to a point near the horizontal axis on the production possibilities curve means more of a product is been produced and less of another product is been produced.
I hope my answer helps you.
