Given p⎯⎯1p¯1 = 0.65,

n1n1 = 441,

p⎯⎯2p¯2 = 0.85,

n2n2 = 378. (You may find it useful to reference the appropriate table: z table or t table)

a. Construct the 99% confidence interval for the difference between the population proportions. (Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answers to 2 decimal places.)

Given the Demand function from Part 1: D(p) = 64 2p , The monopolist's cost is equal to C(Q) = Q2 + 2Q: PART II. Now take the same demand function as in Part I but imagine that the market has two firms instead of 1. Also assume that the marginal cost of each firm is equal to 4. Market structure is therefore characterized as a duopoly. Suppose that firms compete by choosing their output levels simultaneously. (14) (2 points)...

Suppose the market for corn is given by the following equations for supply and demand: QS = 2p − 2 QD = 13 − p

Suppose the market for corn is given by the following equations for supply and demand: QS = 2p − 2 QD = 13 − p where Q is the quantity in millions of bushels per year and p is the price. Calculate the equilibrium price and quantity. Sketch the supply and demand curves on a graph indicating the equilibrium quantity and price. Calculate the price-elasticity of demand and supply at the equilibrium price/quantity. The government judges the...

A particular event has a probability of occurrence of p=0.65. Given 12 independent trials, draw the probability distribution and calculate the expected value. A particular event has a probability of occurrence of p=0.65. If each outcome is independent of the last, draw the probability distribution associated with the event not occurring a given number of consecutive times and calculate the expected value. Given the following scenario, determine which distribution (binomial, geometric, hypergeometric) is the most appropriate to model it? Rank...
