Answer 1

Randomly choose 50 students
- Get a complete list of students, assign each a number, then use a random number generator (or draw 50 numbered slips from a hat) to pick 50. (Or use stratified sampling if you need equal representation by grade.)

Survey design (asking preference)
- Contact the 50 randomly chosen students, show them both soda names (or pictures), and ask “Which do you prefer?” Record answers and basic demographics. No tasting required.

Experiment design (blind taste test)
- Have the 50 randomly selected students taste both sodas in random order, served in identical coded cups so brand is unknown. Randomize order to avoid order effects and ask which they prefer after tasting. Record choices.

(Keep consent and safe procedures in mind.)
