Answer: b. The instrument is correlated with x1.
d. The instrument does not directly influence y, except through x1.
Explanation:
Based on the information given in the question, the necessary characteristics of a suitable instrument include:
• The instrument is correlated with x1.
• The instrument does not directly influence y, except through x1.
Some of the criteria for an instrument variable are the fact that it should have a causal effect on independent variable and also the dependent variable isn't directly affected except through the independent variable which is x1 in this scenario.
Therefore, the correct option are B and D.
Answer:
The correct answer is the option A: Corrective advertising.
Explanation:
To begin with, the concept known as <em>"Corrective Advertising"</em> refers to a severe penalty that is used by many agencies, including the Federal Trade Commision, in ordert to impose to the companies the fact that they had worked unethically regarding certain advertisements that they have been controled by the agency.

Answer:
the interest rate is missing, so I looked for similar questions and found that the semiannual interest rate is 3%.
first of all, we must determine the amount of money that we need to have in our account in order to be able to withdraw $25,000 in 10 years.
You will start making your semiannual deposits today and they will end in exactly 2 years, so we need to find out the present value of the $25,000 in two years:
PV = $25,000 / (1 + 3%)¹⁶ = $15,579.17
that is now the future value of our annuity due:
FV = semiannual deposit x FV annuity due factor (3%, 5 periods)
$15,579.17 = semiannual deposit x 5.46841
semiannual deposit = $15,579.17 / 5.46841 = $2,848.94
