Answer:
Explanation:
Data given and notation
represent the sample mean
represent the standard deviation for the sample
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to determine if the mean is lower than 5600, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
We don't know the population deviation, so for this case is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(1)
t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
Calculate the statistic
We can replace in formula (1) the info given like this:
Complete Question:
What are the benefits of a long-term bond over a short-term bond?
Answer:
c. While long-term bonds have more risks associated with them, they have the potential to bring in higher returns for the initial investment.
Explanation:
A bond can be defined as a debt or fixed investment security, in which a bondholder (investor or creditor) loans an amount of money to the bond issuer (government or corporations) for a specific period of time. The bond issuer are expected to return the principal (face value) at maturity with an agreed upon interest (coupon), which are paid at fixed intervals.
Bonds are generally debts, which may be floated in different ways with respect to the issuer of the bond and its type. Bonds are used by government and corporate institutions to borrow money with interest and they also have to pay for the face value of the bonds at maturity.
Bonds are classified into two (2) main categories and these are;
I. Long-term bonds: they usually spread over a long period of time and as such locking the money of an investor down while availing them a higher interest rate. Also, they are considered to be more riskier than shorter bonds.
II. Short-term bonds: this type of bond mature quickly and as such paying the investor's principal on time. It covers a period of one to five years maximum in duration.
Hence, the benefits of a long-term bond over a short-term bond is that, while long-term bonds have more risks associated with them, they have the potential to bring in higher returns for the initial investment.
Answer:
The question is missing the options which are below:
A Real risk-free rate differences.
B Tax effects.
C Default risk differences.
D Maturity risk differences.
E Inflation differences.
The correct answer is option C,default risk differences.
Explanation:
Default risk is the increase in return given to an investor to compensate the investor for the likely losses that may arise due to the inability of the borrower to make funds available to the investor on the maturity date or even in required amount.
Different debt instruments have different default risk depending on their credit rating as rated by international rating agencies.Such rating is a function of many factors,which includes:
Balance sheet position
Profitability
Liquidity strength of the company
Macro-economic factors and some others.
Liquidity refers to the ability of the company to settle obligations such as repayment of bonds and interest when due.
Invariably,liquidity has a higher impact in determining credit rating as well as default risk of an instrument.
Answer: A. On the curve.
Explanation:
Production possibilities curve (PPC) is simply a graphical representation that is used to show different combinations of two goods which a particular economy can produce when the economy uses the resources it has efficiently.
Points on the curve shows that the resources in an economy are efficiently used, points on the interior of the curve shows that the resources are used inefficiently while the points that are beyond the curve shows are referred to as unattainable.
Therefore, if you are using your factors of production at 100% efficiency, you will be on the curve.
The answer is A.
