A local emergency department sees a mean of 250 adults with concussion each year. What is the probability that there will be 300 or more people with concussion seen in a year? Is it statistically unlikely that there will be 300 or more people with concussion seen in a year? What is the probability that there will be 225 or fewer people with concussion seen in a year? Is it statistically unlikely that there will be 225 or fewer people with concussion seen in a year?

Suppose we know that 42.51% of adults in Canada have high blood pressure. In a sample of 510 adults in Canada, what is the probability of getting a sample proportion of adults with high blood pressure smaller than 0.35? No need to use continuity correction. For this question, give your answer as a PERCENT (not a proportion) rounded to TWO decimal places.

Weapons and Youth A recent study found that 17.5$\%$ of all high school students in the United States have carried a weapon, including a gun, knife, or club. If 1200 high school students are surveyed, what is the probability that more than 200 students, but fewer than 250 , have carried a weapon? Source: Centers for Disease Control and Prevention.
