The correct answer is Only (A) and (C) are true
Explanation:
In a study or research, the control group is the one that does not receive a treatment. This means, in this case, the control group includes those who only drink the green tea without the herbs because they serve as a standard to measure the effects of the herbs. This makes statement A (The "only green tea" group serves as the control group) true; also, the group receiving the herbs is the experimental group.
On the other hand, a double-blind study is one in which the researchers and the participants ignore who is receiving the treatment, which guarantees there is objectivity. This occurs in the study presented because neither the researcher nor the subjects known who received the herbal mix. Thus, statement C (This study is double-blind) is true.
Finally, a study is classified as observational if there is not intervention but the researchers just observe participants to study a phenomenon. This does not occur in the study presented because there is an intervention through the herbal treatment, and therefore the study is not observational.

Answer:
The cost of equity using the DCF method: 4.39%.
The cost of equity using the SML method: 15.01%.
Explanation:
a. The cost of equity using the DCF method:
We have: Current stock price = Next year dividend payment / ( Cost of equity - Growth rate) <=> Cost of equity = Next year dividend payment/Current stock price + Growth rate = 0.3 x 1.04/80 + 4% = 4.39%.
b. The cost of equity using the SML method:
Cost of equity = Risk free rate + beta x ( Market return - risk free rate); in which Risk free rate is rate on T-bill.
=> Cost of equity = 6.3% + 1.3 x ( 13% -6.3%) = 15.01%.
Answer:
C
Explanation:
FDIC gives insurance to depositors. it promises to pay back a certain amount of the deposits of a banks customers in the case where a bank fails. As a result of this insurance banks have a greater incentive to take on more risky projects because they know that their customers would be protected even the project goes sour and the bank fails.
Due to the services of the FDIC, less depositors have lost money when a bank fails because of the insurance services they provide to depositors.
<span>Credit card has slightly lower interest rate.
Let's take a look at both interest rates for 1 year and see what costs more. First, the credit card at 17% apr compounded monthly.
Each month, 17%/12 interest will be taken. The total interest over the year will be
(1 + 0.17/12)^12 = 1.183891728 times the original debt.
Now let's look at the loan from the parents. Over 1 year, you'll be accumulating 2 interest payments. The formula for the year will be
(1 + 0.09)^2 = 1.1881
Comparing the overall rate between the credit card and the parents, the credit card is slightly lower than the parents.</span>
