For a statistics project, Julie distributed a questionnaire and asked her classmates to fill it out. 12 of them did. Is this sample of the students in the class likely to be biased? Choices: (A)yes (B)no

Analyze Sampling Method: Analyze the sampling method used by Julie. Julie asked her classmates to fill out a questionnaire, and 12 of them did. Since she did not use a random sampling method, the students who chose to respond might have different opinions or characteristics compared to those who did not respond. Determine Sample Representation: Determine if the sample is representative. The sample consists only of students who decided to participate, which may not represent the entire class. This could introduce bias in the results, as it might reflect the views of a specific group of students more willing to participate.
