4-55.

Consider the question: “Does a traditional classroom SAT preparation course improve scores more than an online study course?”

Design an experiment that could help to answer this question. Refer to problem 4‑39 for ideas.

When designing your experiment, make sure you have a sample from each respective population of interest, as well as a sample that gets a 'placebo'.
