2. a researcher wants to draw conclusions about the people who live in a city. select all of the surveys that use a random sample. assume that each person asked lives in the city. asking 50 people at the citys library if they like to read. asking every fifth person who arrives at the citys park if they have a smartphone or not. asking every tenth person who walks into the citys shopping mall to vote for their favorite fruit. asking 50 people at the citys community center if they prefer going to the mountains or the beach. asking all of the people at the citys soccer fields to vote for their favorite sport.
Answer
# Brief Explanations:
A random sample should be representative of the entire population (people living in the city). Sampling at places like the library, community - center, soccer fields may attract people with specific interests related to those places. Sampling every fifth person at the park or every tenth person at the mall gives a more random selection as it is not based on a particular interest group.
# Answer:
Asking every fifth person who arrives at the city's park if they have a smartphone or not.
Asking every tenth person who walks into the city's shopping mall to vote for their favorite fruit.
