Jerry thinks that instead of random sampling to conduct an experiment about what students at his middle school think of the cafeteria food, he can just ask ten of his friends. Marcus thinks that random sampling will give a more accurate result because Jerry's friends might all have similar opinions on food because they all hang out together. Who is correct?

Marcus is correct. Random sampling is an important method to ensure that a sample is representative of the entire population. If Jerry only asks ten of his friends, the sample may not accurately reflect the diverse opinions of all the students at the middle school. Jerry's friends may indeed have similar opinions on food due to their social circle, which would result in a biased sample. Random sampling, on the other hand, would provide a better representation of the entire population and increase the likelihood of obtaining accurate and unbiased results.
