Answer:
Quantitative
Explanation:
In quantitative research an observable phenomenon is studied and analyzed via mathematical, statistical, or computational techniques. It is generally done in order to prove or validate a hypothesis. Numerical data is used in this type of research.
In qualitative research non numerical data is recorded by observing phenomena.
Here, the respondents are asked to answer a question according to the scale provided. This data will then be statistically analyzed and conclusions will be drawn hence this type of research is quantitative research.
Answer:
C. a third variable, such as students' home environment, must have caused students to both drink more non-diet soda and engage in aggressive acts
Explanation:
From the question, we are informed about An observational study that was conducted in inner-city Boston approximately four years ago demonstrated that high-school students who consumed more than five cans of non-diet soda every week were between 9 and 15-percent likelier to engage in an aggressive act compared with counterparts who drank less non- diet soda. In this case, we can reliably conclude that a third variable, such as students' home environment, must have caused students to both drink more non-diet soda and engage in aggressive acts.
Observational studies can be regarded as studies whereby
researchers make observation about different effect of factors such as
risk factor, home, as well as environment and diagnostic test that affects the experiment. In observational studies Variables are very crucial, A variable can be anything that that is liable to change, it can change and it can be changed as well. They are factors which the observer can manipulate or control for when carrying out experiments.

Explanation:
Answer: The probability of getting all the questions correct is 1/625 Which is 0.002
Explanation: probability is the possible chance of an event to occur. If Richard has a question the has five options
The probability of Richard to get 1 question correct is
1/5 = 0.2
since 1 option is correct among 5 options given.
Because the answer to each question is independent from the outer question, if he answers the 4 question that means the probability of getting the four question correct will be;
1/5 × 1/5 × 1/5 × 1/5 = 1/625 = 0.0016
To three decimal
0.002
