Question

Accepted Answer

### Part (i) - Target Population
# Brief Explanations:
The target population is the group the survey aims to understand. Here, it's the general population (all people) to know their views on the legislation.
# Answer:
The target population is the general population (all people) who have views on the recent piece of legislation.

### Part (ii) - Sample
# Brief Explanations:
The sample is the group from which data is collected. Here, it's the news website readers who volunteer to take the survey.
# Answer:
The sample is the news website readers who volunteer their opinion in the survey.

### Part (iii) - Random Sample?
# Brief Explanations:
A random sample requires each in the population to have an equal chance to be selected. Here, only readers who volunteer (self - select) are in the sample, so not random.
# Answer:
No, the sample is not collected randomly. Because the sample consists of readers who volunteer to take the survey (self - selected sample), not every person in the general population has an equal chance of being included in the sample.

### Part (iv) - Describe Target Population?
# Brief Explanations:
For data to describe the population, the sample should be representative. A self - selected sample (volunteers) may not represent the general population (e.g., only those with strong opinions or who visit the site volunteer), so data can't be used to describe the target population.
# Answer:
No, the data collected from the sample cannot be used to describe the target population. Since the sample is a self - selected (volunteer) sample, it is likely to be biased (e.g., it may over - represent people with strong opinions about the legislation or people who frequently visit that news website) and does not accurately represent the views of the entire general population.
