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:
Mortgage, 20%, 80%
Explanation:
Typically required on Mortgage loans when the down payment is less than 20% and loan-to-value ratio is in excess of 80%. Loans with higher LTVs don't conform to Fannie Mae/Freddie Mac guidelines, so a lender may require PMI to offset the risk.

Interest Factors
<u>Periods 6% 7% 8% 9% 10% 11
%</u>
1 1.0600 1.0700 1.0800 1.0900 1.1000 1.1100
2 1.1236 1.1449 1.1664 1.1881 1.2100 1.2321
3 1.1910 1.2250 1.2597 1.2950 1.3310 1.3676
4 1.2625 1.3108 1.3605 1.4116 1.4641 1.5181
1)
Future value paying simple interest = Principal + [( principal * interest) * investment period]
Future value paying simple interest = $2,000 + [ ( $2,000 * 9%) * 3]
Future value paying simple interest = $2,000 + 540
Future value paying simple interest = $2,540
2)
Future value paying compound interest = Present value * ( 1 + interest)n
Future value paying compound interest = $2,000 * ( 1 + 0.09)3
Future value paying compound interest = $2,000 * 1.295029
Future value paying compound interest = $2,590.058
3)
Difference = $2,590.058 - 2,540
Difference = $50.058
The financial meltdown of 2008 was in part due to <u>quants </u>demonstrating the dangers of relying too heavily on the quantitative techniques of scientific management.
<h3>How did the financial meltdown of 2008 happen?</h3>

Quants were quantitative models that were used to decide on the financial assets to invest in. They failed to predict the risks associated with Mortgage Backed Securities and this contributed in part to the meltdown.
