It can be deduced that the expected rates of return of stocks A and B are 13.2% and 7.7% respectively.
<h3>
How to calculate the expected
rates of return</h3>
E(RA) = 0.1 (10%) + 0.2 (13%) + 0.2 (12%) + 0.3 (14%) + 0.2 (15%)= 13.2%
E(RB) = 0.1 (8%) + 0.2 (7%) + 0.2 (6%) + 0.3 (9%) + 0.2 (8%)= 7.7%
Therefore, the expected rates of return of stocks A and B are 13.2% and 7.7% respectively.
The standard deviation will be calculated thus:
Var(RA) = [0.1 (10%-13.2%)² + 0.2 (13%-13.2%)² + 0.2 (12%-13.2%)² + 0.3 (14%-13.2%)² + 0.2 (15%-13.2%)2 ] 1/2
= 1.5%
Var(RB) = [0.1 (8%-7.7%)² + 0.2 (7%-7.7%)² + 0.2 (6%-7.7%)² + 0.3(9%-7.7%)² + 0.2 (8%-7.7%)² ] 1/2
= 1.1%
Therefore, the standard deviation of stocks A and B are 1.5% and 1.1% respectively.

The act of providing a loan by the banker to the borrower amounting to $800 after setting aside the reserve amount of $200 contributes to the increase of the money supply by $800.
<h3>What is the money supply?</h3>
The money supply is the amount that a public held at a point in time including currency notes, coins, and the bank account balances.
When the banker is giving the loan to the borrower at $800 then it infuses the money into the economy as this amount is further given as a loan by another bank to another borrower. This whole cycle goes on to continue till the amount reaches zero.
Therefore, the money supply increases by $800 when the banker gives loans to the borrower for the amount of $800.

Answer:
I waive any possibility of compensation for injuries that I may receive as a result of participation in this research.
Explanation:
The given definition in the scenario is that ''Exculpatory language is that which <u>waives or appears to waive any of the subject's legal rights</u> or releases <u>or appears to release those conducting the research from liability for negligence</u>.''
Therefore in the consent statement requesting that a subject state ''I <u>waive any possibility of compensation for injuries that I may receive as a result of participation</u> in this research, directly defines the content of an exculpatory language.
The statement is waiving the responsibility of researchers for negligence and at the same time waiving the legal rights of the research participants
