Understand the problem: Understand the problem. We need to find out what percentage of students would pick vegetarian meals. We're choosing between two survey methods.
Evaluate option A: Evaluate option A. Sorting students randomly and asking the first 35 gives every student an equal chance to be selected. This is a random sampling method.
Evaluate option B: Evaluate option B. Asking the first 35 students in line might not be random because these students could have something in common, like arriving early, which could bias the results.
Decide method: Decide which method is better. Random sampling (option A) is more likely to represent the whole student body without bias.
