Question: A school principal would like to evaluate whether the temperature of a classroom affects learning. She asks 3 classrooms (with 5 students in each classroom)

A school principal would like to evaluate whether the temperature of a classroom affects learning. She asks 3 classrooms (with 5 students in each classroom) to participate in the experiment, receiving an hour-long videotaped lesson. One of the classrooms is kept at a constant temperature of 60 degrees, the other at 70, and the last at 80 degrees. After the lesson, students all receive the same quiz to test their acquisition of material. Below is their data. Test the hypothesis that room temperature affects test performance using an alpha level of .05.

What test is appropriate?

What is the Null Hypothesis?

What is the Alternative Hypothesis

What is (are)the critical value(s)?

What is the obtained statistic?
