Answer:
The correct option is D) The design of the study suffers from selection bias.
Explanation:
In research, Selection Bias occurs when the researcher decides who the respondents are or those who are being evaluated or studied.
Every research ought to be designed in such a way that the respondents are selected at random.
In the information provided, the respondents were selected from a group of people who on a balance of probability were already inclined to decline because it was a list of dissatisfied customers. The chances of them declining to respond or responding with a negative were higher than the chances of them indicating that they would buy and this defeats the purpose of the research. The research ought to have also included a sample of respondents who didn't have the product, who had enjoyed the services of the company and were content, those who didn't even know what the product did until they got the survey.
That way holistic information can be obtained from the research about how different sets of people will react and not just those who are already dissatisfied with the company's product(s).
Some of the ways to avoid selection bias in research are:
- To employ the use of random techniques selecting sample sets from populations.
- To check that the traits or characteristics of the larger population are well represented in the samples selected

Answer:
Beta= 1.26
Explanation:
<u>First, we will calculate the proportion of the portfolio of each security:</u>
Security A= 600/1,000= 0.6
Security B= 400/1,000= 0.4
<u>Now, the beta of the portfolio:</u>
Beta= (proportion of investment A*beta A) + (proportion of investment B*beta B)
Beta= (0.6*1.5) + (0.4*0.9)
Beta= 1.26
Entrepreneurs are people that make their own business. Most businesses tend to have a rough start and can possibly even fail. It depends on how the person creating the business acts and how determined they are to make the business flourish. Although many rich people may of started off of just one product that got advertised well and was sold quickly. Even if it isn't a product but more so a service, you can be very successful. Just know what the people want.
Hope this helped!

The IRR is the rate of return that equates the cost of the project to the present value of cash flows receivable from the project in future.
Using an excel approach, the formula formula IRR is given as:
=irr(values)
The values in this case are
-$1300 in year 0
$450 in year 1
