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:

If the Fed mailed everyone a $1,000, the effect would be a <u>rise in prices, </u>output, and income.
<h3 /><h3>What happens when money is injected into the economy?</h3>
The Equation of exchange is:
<em>Money supply x Velocity of money = Price level x Quantity of goods and services produced </em>
If the Money supply increases like it will when $1,000 is sent by the Fed to people, the velocity will also rise as people purchase more goods and services.
The Price level and the Quantity produced on the right side of the equation would also have to rise to match the left side. So prices would rise, and so would output.
