Historically, a factory has been able to produce a very specialized nano-technology component with 35% reliability, i.e., 35% of

the components passed its quality assurance test. They have now changed their manufacturing process and hope that this has improved the reliability. To test this, they took a random sample of 24 components produced using the new process and found that 13 components passed the test. If you do a hypothesis test to see if the new manufacturing process is more reliable, does this observation give you enough evidence to reject the null hypothesis at 5% level of significance? (Suggestion: Use Microsoft Excel for your calculations.)The table below shows the probability of observing number of components (X) passing the test out of 24 components, if the reliability is 35%.X Probability0 0.00001 0.00042 0.00263 0.01024 0.02895 0.06226 0.10617 0.14708 0.16829 0.161010 0.130011 0.089112 0.052013 0.025814 0.010915 0.003916 0.001217 or more 0.0004A) NoB) Yes

Answer:

Yes

Explanation:

From the given output

The  Probability of getting 13 or more passed

when the  reliability = 0.35. can be calculated as follows

=0.0258+0.0109+0.0039+.0012+0.0004 = 0.0422   ≈  4.2%

Since the probability is less than the  5% level we will therefore reject the Null hypothesis  

answer : YES

A point outside (to the right of) the production possibilities curve of a nation implies that this nation is using its resources
PtichkaEL [24]

Answer:

is not attainable for this nation

Explanation:

The Production possibilities frontiers is a curve that shows the various combination of two goods a company can produce when all its resources are fully utilised.  

The PPC is concave to the origin. This means that as more quantities of a product is produced, the fewer resources it has available to produce another good. As a result, less of the other product would be produced. So, the opportunity cost of producing a good increase as more and more of that good is produced.

Point outside the curve or to the right of the curve means that the production level is not attainable given the level of resources

Points inside the production possibilities curve means that the nations resources are not being fully utilised

Factors that cause the PPF to shift  

1. changes in technology.  

2. changes in available resources.  

3. changes in the labour force.

Answer:

The correct answer is letter "B": A decrease in a deferred tax asset.

Explanation:

A Deferred Tax Asset is an asset on a balance sheet of a business that can be used to lower taxable income. It is the opposite of deferred tax liability that reflects something that will increase income taxes. Both are listed under current assets on the Balance Sheet.

The deferred tax asset will be generated when recorded income taxes owed are higher than the income taxes paid to the Government.

Thus, <em>a decrease in deferred tax is recorded when a company has collected revenue in advance for a good not delivered or a service not rendered yet.</em>

jasenka [17]

Answer:

The interest paid on loan was at floating rate which means that the investor earning was lower because of lower interest rate than the interest rate he was expecting.

Explanation:

Because the bond was dependent on the floating rate in the market. The borrower kept paying the investor at the floating rate not at the fixed rate which would had increased its investment worth to $1800. As $1600 is less than $1800 so the interest rate agreed was floating rate interest.
