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 sections. section 1 (traditional classroom) consisted 101 students and section 2 (online class) were 105 students. At the end of the semester the researchers measured 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.

A team of researchers has developed a new weight loss
supplement. They want to know if patients who use the new
supplement for four weeks lose any weight. The supplement has some
minor side effects including mild headaches and achiness. If the
researchers obtain evidence of weight loss they will proceed to
produce the supplement commercially and sell it for a large profit.
If they do not obtain evidence of weight loss, the project will be
ended.
