Which error could have been committed? (A) Type I error: Conclude that more than 50% of students want earlier lunch, when 50% or less want earlier lunch. (B) Type I error: Conclude that more than 50% of students want earlier lunch, when more than 50% want earlier lunch. (C) Type II error: Fail to reject that 50% of students want earlier lunch, when more than 50% want earlier lunch. (D) Type II error: Fail to reject that 50% of students want earlier lunch, when 50% or less want earlier lunch. (E) Type II error: Fail to reject that more than 50% of students want earlier lunch, when 50% or less want earlier lunch.
