Video pinball A student runs an experiment to test how different factors affect his score while playing video pinball. Here are the results of 16 runs of an experiment performed in random order. Factor Eyes has two levels: both open and right eye closed. Factor Tilt has two levels: tilt on and tilt off. The response is the score of one ball at a combination of factors. Each combination was repeated 4 times in random order.

1. What are the null and alternative hypotheses for the main effects?

2. Analyze the data and write a short report on your findings. Include appropriate graphics and diagnostic plots.
