If workers and firms have rational expectations, they understand that ________ monetary policy will raise the inflation rate, so

Deffense [45]

Answer:

expansionary; will be equal to

Explanation:

Remember, monetary policies are basically divided into:

expansionary monetary policy, and
contractionary monetary policy.

Indeed, as the name implies, the expansionary monetary policy is meant to in a sense boost up economic growth in terms of reducing interest rates thereby theoretically increasing spending and also leading to an increase in the money supply. When there is an increase in the money supply, this thus leads to an increased inflation rate, which would be expected if workers and firms have rational expectations.

A lottery claims its grand prize is $15 million, payable over 5 years at $3000000 per year. If the first payment is made imm

xz_007 [3.2K]

Answer:

$ 11, 978,133.75

Explanation:

The grand prize of 15,000,000 is worth the present value of the prize at an 8% interest. The prize is paid every year, meaning its an annuity case.

The present value of an annuity is calculated using the formula

PV = P × 1 − (1+r)−n

r

Where

P $3,000,000

r is 8% 0r 0.08

n is 5

PV = $3,000,000 x 1-(1+0.08) - 5

0.08

PV =$3,000,000 x 1 - 0. 6805831

0.08

PV = $ 3,000, 000 x 3.99271

PV = 11, 978,133.75

The College Board reported the following mean scores for the three parts of the Scholastic Aptitude Test (SAT) (The World Almana

storchak [24]

Answer:

a) $P(492$

And we can use excel or the normal standard table to find this probability:

$P(-0.949 < Z< 0.949)= P(Z$

b) $P(505$

And we can use excel or the normal standard table to find this probability:

$P(-0.949 < Z< 1.898)= P(Z$

c) $P(484$

And we can use excel or the normal standard table to find this probability:

$P(-1 < Z< 1)= P(Z$

Explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Part a

Let X the random variable that represent the scores for critical reading of a population, and for this case we know the distribution for X is given by:

$X \sim N(502,100)$

Where $\mu=502$ and $\sigma=100$

We select a sample of size n=90, since the distribution for X is normal then the distribution for the sample size is also normal

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}}=\frac{100}{\sqrt{90}}=10.54)$

And for this case we want this probability:

$P(502-10 < \bar X < 502+10)$

And for this case we can use the z score given by:

$z= \frac{\bar X -\mu}{\sigma_{\bar x}}$

And if we use this formula we got:

$P(492$

And we can use excel or the normal standard table to find this probability:

$P(-0.949 < Z< 0.949)= P(Z$

Part b

Let X the random variable that represent the scores for Math of a population, and for this case we know the distribution for X is given by:

$X \sim N(515,100)$

Where $\mu=515$ and $\sigma=100$

We select a sample of size n=90, since the distribution for X is normal then the distribution for the sample size is also normal

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}}=\frac{100}{\sqrt{90}}=10.54)$

And for this case we want this probability:

$P(515-10 < \bar X < 515+10)$

And for this case we can use the z score given by:

$z= \frac{\bar X -\mu}{\sigma_{\bar x}}$

And if we use this formula we got:

$P(505$

And we can use excel or the normal standard table to find this probability:

$P(-0.949 < Z< 1.898)= P(Z$

Part c

Let X the random variable that represent the scores for Writing of a population, and for this case we know the distribution for X is given by:

$X \sim N(494,100)$

Where $\mu=494$ and $\sigma=100$

We select a sample of size n=100, since the distribution for X is normal then the distribution for the sample size is also normal

$\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}}=\frac{100}{\sqrt{100}}=10)$

And for this case we want this probability:

$P(494-10 < \bar X < 494+10)$

And for this case we can use the z score given by:

$z= \frac{\bar X -\mu}{\sigma_{\bar x}}$

And if we use this formula we got:

$P(484$

And we can use excel or the normal standard table to find this probability:

$P(-1 < Z< 1)= P(Z$

Suppose the current price of a good is $55. At this price, the quantity supplied is 165 units, and the quantity demanded is 240

inysia [295]

Answer:

190

$60

Explanation:

Equilibrium price is the price at which quantity demanded equals quantity supplied

Equilibrium quantity is the quantity at which quantity demanded equals quantity supplied

Let x = change in quantity supplied

the following equations can be derived from the question

165 + 5x = total change in quantity supplied

240 - 10x = total change in quantity demanded

At equilibrium, quantity demanded equals quantity supplied. So,

165 + 5x = 240 - 10x

collect like terms and solve for x

15x = 75

x = 5

this means that quantity supplied would have to increase 5 times : 165 + 5(5) = 190

and quantity demanded would have to decrease 5 times : 240 + 10(5) = 190

equilibrium quantity is 190

equilibrium price = $55 + 1(5) = $60
