a newspaper writer will write an article about the mean age of voters. she will estimate by selecting a sample of voters and calculating their mean age. which method should the writer use to select the sample? select 100 people who voted for the most popular candidate in the last election randomly select 100 people who read the newspaper select 100 people who voted in the last election and are more than 30 years old randomly select 100 people who voted in the last election
Answer
# Brief Explanations:
To estimate the mean age of voters accurately, the sample should be representative of all voters. Selecting only those who voted for a popular candidate, who read the newspaper, or are over 30 years old would introduce bias. Randomly selecting people who voted in the last election gives a more representative sample.
# Answer:
randomly select 100 people who voted in the last election
