Randomized control triat + regression analysis (1 of 1) In the mid-1980s, the state of Tennessee conducted an experiment, known as Project STAR, to better understand how class sizes affect student achievement. Elementary school students were randomly assigned to classes of different sizes students in the treatment group were placed in a small class and students in the control group were placed in a regular sized class The researchers analyzed the results of the experiment using regression techniques Reading score (points) (1) (2) Treatment 5.87 (104) 434.69 (071) 5.86 (100) HIS (132) Intercept Boy Free Lunch Black 1652 (111) -8.74 (119) 0.33 (0.00) Teacher experience (years) Observations 3,715 3715 Note Standard errors in parenthese Using the information in the regression table and your knowledge of randomised control trials and regression analysis, please respond to each of the following questions 1.
