In addition, digital certification service can also be used to ensure the authenticity of the other party. The standards for processing financial transactions quite strict enough to ensure safeguarding the interests of the card issuer, the cardholder and the merchant.

GenaCL600 [577]

Answer:

a. ½(Y² - Y) is an unbiased estimator of the variance.

b. 2 Standard Error = 2√(Y²/2 - Y/2)

Explanation:

Given

E(Y) = 1/p

V(Y) = (1 - p)/p²

Simplifying V(Y)...

V(Y) = 1/p² - 1/p

Because V(Y) = 1/p² - 1/p and E(Y) = 1/p,

We'll guess that there might be an unbiased estimator of shape

aY² + bY.

Solving E(aY² + bY)...

First, E(Y²) = V(Y) + (E(Y))²

Substituting the values of V(Y) and E(Y);

E(Y²) = 1/p² - 1/p + (1/p)²

E(Y²) = 1/p² - 1/p + 1/p²

E(Y²) = 2/p² - 1/p

With the above,

E(aY² + bY) is then equal to

E(aY² + bY) = 2a/p² - a/p + b/p

The above equation is equal to V(Y), if and only if

a = ½ and b = -½

-------------- Checking------------

Let E(aY² + bY) = V(Y)

i.e.

2a/p² - a/p + b/p = 1/p² - 1/p

Multiply through by l

2a/p - a + b = 1/p - 1

Comparing right hand side to left hand side

2a/p = 1/p ----- Equation 1

And

- a + b = - 1 ------- Equation 2

Solving Equation 1 (Multiply both sides by p)

2a = 1

So, a = ½

Substitute ½ for a in Equation 2

-½ + b = -1

b = -1 + ½

b = -½

------------ End --------------

Thus ½(Y² - Y) is an unbiased estimator of the variance.

b.

2 Standard Error is given by

2√V(Y)

= 2√(1/p² - 1/p)

= 2√(Y²/2 - Y/2)

If the Federal Reserve announces that its target for the federal funds rate is rising from 4 percent to 4.25 percent, how do you
olganol [36]

Answer:

B) As long as the Fed's announcement is credible, workers and firms will reduce their consumption and investment spending, which will reduce aggregate demand and reduce inflation.

Explanation:

If the FED announces that it will increase the federal funds rate, it will increase the interest that banks charge other banks for lending them money in order to  comply with the reserve ratio. This increase would make banks hand out less loans and be more careful in order to reduce their need for overnight funds.

If banks reduce their loans, their capacity for creating money will also be reduced, lowering the consumption level and investment spending of both workers (households) and private firms.

olganol [36]

Answer:

FV= $772

Explanation:

Giving the following information:

Initial investment (PV)= $850

Interest rate (i)= 3.5% = 0.035

Number of periods (n)= 5 years

<u>To calculate the future value (FV), we need to use the following formula:</u>

FV= PV*(1+i)^n

FV= 650*(1.035^5)

FV= $772
