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'.
