If the local union contract has a clause requiring that the mine be shut down as soon as three workers incur lost-work injuries, on what percentage of the days will the mine be operational throughout the day?
- What should I do for question 10 and 11?For questions 4 and 5, determine whether the study is observational or an experiment. If the study is an experiment, identify the control and treatment groups, and whether blinding is needed. If the study is observational, state whether it is a case-control study, and if so, identify the cases and controls. There is a suspicion that zinc oxide, the white non-absorbent sunscreen traditionally worn by lifeguards, is more effective at preventing sunburns that lead to skin cancer than absorbent sunscreen lotions. A case-control study was conducted to investigate if exposure to zinc oxide is a more effective skin cancer prevention measure. The study involved comparing a group of former lifeguards that had developed cancer on their cheeks and noses (cases) to a group of lifeguards without this type of cancer (controls) and assess their prior exposure to zinc oxide or absorbent sunscreen lotions.(c) Find the number of these patients that were smokers but had neither high blood pressure nor high cholesterol levels. (d) Find the number of these patients that did not have exactly two of the indications listed.
