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:
Answer:
C, a decrease in the real interest rate
Explanation:
When factors such as changes in expectation, technology, demands for goods and services, etc cause in shift in the demand curve for capital, interest rates act as the determinant of the capital demand.
If the interest rates of loans are high, capital demand will be reduced but in the event that interest rates are low, capital demand is high or increases.

<span>What Supreme Court decision overturned Plessy v. Ferguson?
</span><span>A. Brown v. Board of Education</span>
Answer:
$50 and $2
Explanation:
The computation of the total revenue and the marginal revenue is shown below:
Total revenue is
= Price × quantity
= $2 × 25
= $50
And, the marginal revenue is received collected from one unit i.e price of the one units that equivalent to $2
Hence, we simply applied the above formula to determine the total revenue and the marginal revenue
Answer:
defective
Explanation:
In an electronic firm it is necessary to keep check for every circuit as they turn out to be defective. There can be minor error is circuit formation but this will be considered as defective because circuits are very sensitive and even minor error can lead to short circuits which could lead to a disaster. It is necessary for a firm to keep track and quality of every circuit should be checked.
