You are working part-time at a road construction firm. your boss knows you are learning some statistics in your classes this semester and calls you into the office. he says, "we've taken sample densities from loads of asphalt we've gotten from our supplier. the information from their company says their process produces a consistent density with a standard deviation of 2.65 pounds per cubic foot. here's the data we've collected. can you give me an estimate of the average density that our supplier's process is producing? i want to be 80% confident of the range you provide."

Afirm produces a product in a competitive industry and has a total cost function (tc) of tc(q) = 60 + 10q + 2q2 and a marginal cost function (mc) of mc(q) = 10 + 4q. at the given market price (p) of $20, the firm is producing 5.00 units of output. is the firm maximizing profit? no what quantity of output should the firm produce in the long run? the firm should produce unit s) of output. (enter your response as an integer.)

The market price of cheeseburgers in a college town increased recently, and the students in an economics class are debating the cause of the price increase. some students suggest that the price increased because the price of beef, an important ingredient for making cheeseburgers, has increased. other students attribute the increase in the price of cheeseburgers to a recent increase in college student enrollment.1. the first group of students thinks the increase in the price of cheeseburgers is due to the fact that the price of beef, an important ingredient for making cheeseburgers, has increased. (what happened to demand and supply, shift to the right or left)2. the second group of students attributes the increase in the price of cheeseburgers to the increase in college student enrollment. (what happens to demand and supply, shift to the right or left)3. suppose that both of the events you analyzed above are partly responsible for the increase in the price of cheeseburgers. based on your analysis of the explanations offered by the two groups of students, how would you figure out which of the possible causes was the dominant cause of the increase in the price of cheeseburgers? (choose a, b,c, or d)a)if the price increase was small, then the supply shift in the market for cheeseburgers must have been larger than the demand shift.b)if the equilibrium quantity of cheeseburgers decreases, then the demand shift in the market for cheeseburgers must have been larger than the supply shift.c)if the equilibrium quantity of cheeseburgers decreases, then the supply shift in the market for cheeseburgers must have been larger than the demand shift.d)whichever change occurred first must have been the primary cause of the change in the price of cheeseburgers.
