Question

A piano teacher is interested in knowing how many of her students plan to take time off from lessons during the summer months. She surveys each student on Monday and determines that about 50% of her students plan to take time off.
She then repeats her study with her students on Tuesday, Wednesday, Thursday, and Friday. All surveys yield the same results. What generalization can the piano teacher make?
