Expert Solution

1-b- Hypothesis

A hypothesis is a tentative statement what the researcher predicts. There are mainly two types of hypothesis, null hypothesis and alternative hypothesis.

2-c-Allowed so long as participants will not be harmed and the knowledge gained clearly outweighs the use of dishonesty

Most psychologists have concluded that deception is permissible, provided that two basic principles are followed. The first of these is known as informed consent, and requires that research participants be provided with information about all the events and procedures a study will involve before they agree to participate in it, and that they be informed that they are completely free to leave at any time.

The second principle is known as debriefing, and requires that research participants be given full information about all aspects of a study after they have participated in it. Debriefing ensures that participants in psychological research leave with a full understanding of its purpose, and that they receive any information that was temporarily withheld from them.

3-C- protect the rights of of human and animal subjects.

The main focus of any research is to protect the rights of subjects.

4-B- yes

Informed consent requires that research participants be provided with information about all the events and procedures a study will involve before they agree to participate in it, and that they be informed that they are completely free to leave at any time.

The efficient markets hypothesis (EMH), known as the Random Walk Theory, is the proposition that current stock prices fully reflect available information about the value of the firm, and there is no way to earn excess profits, by using this information. However, the pandemic covid-19 might challenge this theory. In relation to that, you are asked to test whether the different forms of EMH (weak, semi strong and strong forms) on the stock exchange of Mauritius. Test the semi strong...
