Answer
# Brief Explanations:
## Part A
The sample is from a community meeting about playground conditions. People attending such a meeting are more likely to have young - children as they are concerned with playground - related issues. So, it's a biased sample and not representative of the whole population.
## Part B
A possible method is to randomly select households from the entire community using a random number generator to pick addresses. Then, contact the selected households and ask if they have young children. This would be representative because it gives every household in the community an equal chance of being selected, reducing bias.
# Answer:
## Part A
The sample is from a meeting about playground conditions, so those attending are more likely to have young children, making it a biased and non - representative sample of the whole population.
## Part B
Randomly select households from the entire community using a random number generator for addresses and contact them to ask about young children. This gives every household an equal chance of being selected, reducing bias and providing a more representative sample.
