Question: You’re a fourth-grade teacher, and you’ve saved extensive records of all your students for the past five years. Assume that your students are a sample of all fourth-graders in your state. For each of the following questions, state what test to use, how you would set up the data and the Ho/Ha if applicable. Please use full sentences.

You have a nagging idea that shorter students tend to have better grades; maybe you could roughly predict a new student’s final grade by their height? And how accurate might that prediction be?
