Refer to the accompanying data table, which shows the amounts of nicotine (mg per cigarette) in king-size cigarettes, 100-mm menthol cigarettes, and 100-mm nonmenthol cigarettes. The king-size cigarettes are nonfiltered, while the 100-mm menthol cigarettes and the 100-mm nonmenthol cigarettes are filtered. Use a 0.05 significance level to test the claim that the three categories of cigarettes yield the same mean amount of nicotine. Given that only the king-size cigarettes are not filtered, do the filters appear to make a difference? Click the icon to view the data table of the nicotine amounts. Determine the null and alternative hypotheses.

In a Munich high school, A class has 20 students, the instructor gave two exams, one take home exam and one live exam. He inspected the answers of the students and scored them for their similarity to rest of the class. (in the picture) Was the similarity of the answers higher in the Take Home exam or Live Exam? Perform a hypothesis test on differences to make your decision, use α = 0.05.(Non-parametric Test)
