In the US economy, nearly half of all workers employed by private firms work at the 0.3% of firms that have 500 or more employees.
What does this relationship mean for the power relationship between large firms and the labor force?
What do you think these large firms having such a market share of labor means for labor prices (wages)?
Can you propose a policy that would counteract this power imbalance?

The red blood cell counts (in millions of cells per microliter) for a population of adult males can be approximated by a normal distribution, with a mean of 5.1 million cells per microliter and a standard deviation of 0.3 million cells per microliter. (a) What is the minimum red blood cell count that can be in the top 28% of counts? (b) What is the maximum red blood cell count that can be in the bottom 13% of counts??

You work for a breakfast cereal manufacturer. Your job is to decide if the new machinery is overfilling the cereal boxes. You take a sample of 37 randomly selected boxes and find that the mean weight for the sample is 1.6 lbs with sample standard deviation 0.3 lbs. The boxes are supposed to weigh 1.5 lbs. Conduct a hypothesis test at the α = 0.01 significance level. Be sure to state your conclusion in context.

The government has implemented a new policy to support the price of barley at $5.68/bu. If the barley market equilibrium price is $3.52/bu, the equilibrium quantity of barley is 1,117.00 million bu, the elasticity of supply is 0.3, and the elasticity of demand is -0.75, then what is the new quantity supplied and the new quantity demanded at the support price? How much barley would the government need to buy to keep the price supported at $5.68/bu?
