A Minnesota school district has a novel idea about a factor influencing school attendance: they think the more the school cafeteria serves “junkie” kid preferred food, the more they want to come to school. To test this, they take a sample of eight school days and measure the % of saturated fat in the school lunch and the % school attendance. The students are told in advance what the school lunch will be.
Evaluate the data and then explain if serving tasty, yet lousy,
food is related to attendance.

During World War II, an Allied soldier named Robert Radford
spent several years in a large German prisoner-of-war (POW) camp.
At times more than 50,000 prisoners were held in the camp, with
some freedom to move about within the compound. Radford later wrote
an account of his experiences. He described how an economy
developed in the camp, in which prisoners traded food, clothing,
and other items. Services such as barbering also were exchanged.
Lacking paper money, the prisoners began to use cigarettes
(provided monthly by the Red Cross) as money. Prices were quoted,
and payments made, using cigarettes.
(a) In Radford’s POW camp, explain how cigarettes fulfilled the
three main functions of money
(b) Briefly discuss why a non-smoking prisoner would have been
willing to accept cigarettes in exchange for a good or service in
Radford’s camp. (2 ma

Scenario 1: You see a skateboarder going down a hill and suddenly lose control, crashing into the gravel on the side of the bike path. The skateboarder was wearing a helmet and did not hit their head on the ground when they fell. You walk over to the skateboarder to see if you can help them and notice them struggling to sit up and moaning in pain. You notice blood on the pavement and look to find a large deep gash on the skateboarder’s thigh that is spurting blood. You are first aid certified and want to help. (1) What are the initial steps you should take when responding to this emergency? (2) How would you determine what your plan of care would be, and how would you care for the victim? Describe in detail.
Scenario 1 Continued: You have been applying pressure to the thigh with gauze pads, but the bleeding still continues and is still spurting. (1) With this new information how would you change your care? Describe in detail.
Scenario 2: You are playing a pickup game of basketball with your friends. During the game, one of the players trips over an untied shoelace and falls forward. As they are falling, they put their hands out in front of them to break their fall. They fall to the ground then yell in pain. You look over at them and they are sitting on the ground holding their arm close to their body. When you look at the arm you can see that their elbow is pointed at a weird angle and there is an obvious bump on the back of it. The athlete says that they felt a pop and they are unwilling to move their arm. (1) Describe in detail the initial steps you would take in this situation. (2) Explain how you would determine what your plan of care for the athlete should be.
Scenario 2 Continued: You have determined that the athlete has dislocated their elbow and they need more medical attention. (1) Explain what steps you would take when giving care for the athlete. (2) When would you stop providing care for the athlete?
