Can you please check my work?
A city planning committee surveys 100 people waiting at a bus stop about the expansion of the public transportation system.
Is this an example of a: random sample, systematic sample, self-selected sample, convenience sample, bipartisan sample, or stratified random sample?
I think that it's an example of a convenience sample.
Volunteers stop to survey residents of every fourth house from the end of each block in town.

This is Algebra 1 where ?
This is so late but yep, you're all correct.
I just wanted to put it out there though and say that I can't believe you take all those hard courses in our school, I bailed out of Physics to hurry and get it over with so
no
To check your work, let's determine the type of sampling method used in each scenario.
Scenario 1:
A city planning committee surveys 100 people waiting at a bus stop about the expansion of the public transportation system.
You mentioned that this is an example of a convenience sample. You are correct! A convenience sample is a non-probability sampling method that involves selecting individuals who are readily available and easy to reach. In this case, the surveyors simply approached the people already present at the bus stop, making it a convenience sample.
Scenario 2:
Volunteers stop to survey residents of every fourth house from the end of each block in town.
You mentioned that this is an example of a systematic sample. You are correct again! A systematic sample is a probability sampling method where the sample is selected systematically. In this scenario, every fourth house from the end of each block is surveyed, indicating a systematic approach.
Great job on identifying the correct sampling methods for both scenarios!
