Question

3. A team of educational researchers want to assess the learning outcomes of courses that are offered in traditional face-to-face classroom as compare with online options. Students enrolled in a course randomly assigned to traditional and online sections. Section 1 (traditional classroom) consisted 101 students and section2 (online class) were 105 students. At the end of the semester the researchers measured the achievement scores. Students in section 1 had an average of 85 with standard deviation of 6.5 and section 2 (online) earned an average of 78.0 with standard deviation of 9.5. is there a significant difference between the traditional and online class outcomes? At 95% level, apply five-step hypothesis testing and interpret the result.
