D. A random sample
Step-by-step explanation:
The answer to your question is D. A random sample because this sampling type is people being randomly selected from the population. We can also rule out the other options because of the following reasoning:
[✗] A. A convenience sample
-> This is a good contender, but as she is not asking everyone and the sample is <em>for</em> the school, it would not make sense to ask people near her house for example, we can say that this probably is not the best option.
[✗] B. A self-selected sample
-> This type is more like a poll, people volunteer for a self-selected sample, while here they are being asked
[✗] C. A systematic sample
-> Every so often she is asking students questions, she does not have a set number of how often or of the population (that we know of)
[✓] D. A random sample
-> This option is correct as stated above. She is randomly picking people.
Have a nice day!

Answer:
D,All of the above.
Step-by-step explanation:
A beta coefficient measures the degree of the volatility, or systematic risk, of an individual stock in comparison to the unsystematic risk in market terms of the entire market. In statistical terms, beta represents the slope of the line through a regression of data points from an individual stock's returns against those of the market.it also measures systematic risk as it is the volatility that affects many industries, stocks, and assets e.t.c. Systematic risk affects the overall market and it is a challenge to predict. Unlike with unsystematic risk, diversification cannot help to smooth systematic risk, because it affects a wide range of assets and securities. For example, the Great Recession was a form of systematic risk; the economic downturn affected the market as a whole.
