Question
11. Math-54 sections that are classified as Scheduled, Scheduled for Exams, or Flexible,
were sampled to see if the means on a common final were different. A one-way Analysis
of Variance (ANOVA) was performed on the collected data to determine if the null
hypothesis (uscheduled = Hscheduled Exam = Hflexible) should be rejected or not. The samples are
normally distributed.
а.
