I am confused by this question.
The principal announced that 50% of the children in Ms. Stanzi's class met their reading goal for the month and that 55% of the children in Ms Lowrey's class met their reading goal for the month. Ms Stanzi said that a greater number of her students met their reading goal. Could Ms Stanzi be correct? Why or Why not.
Miss Stanzi could be correct. her thought would only be right if she had a greater number of students in her class than Miss Lowery's. For instance, if Miss Stanzi had 30 children in her class 15 people would have accomplished the goal. If Miss Lowery had 25 only 13 students would have accomplished it.
