A university is concerned with its student’s first year mean GPA. They implement new guidelines in the hopes of improving the overall students performance. To verify the guidelines’ effectiveness, they would like to sample a number of students and infer on their first year mean GPA. Previous work has determined that the standard deviation is 0.3. They would like a 98% confidence for their experiment and a margin of error of 0.15. What is the sample size required for this experiment?
