Exercise require the use of computer and software. A study by researchers at North Carolina State University found thousands of errors in 12 of the most widely used high school science texts. Philip Sadler, director of science education at the Harvard-Smithsonian Center for Astrophysics, recorded the physics marks of college students who had used a textbook in high school and the marks of students who did not have a high school textbook. Data are given in Study performance. xlsx. Do these data allow us to infer that students without high school textbooks in science outperform students who used textbooks? Significance level is 5%.
