In Smalltown, Pennsylvania, the demand function for men’s haircuts is Qd=500−30p+0.08Y, where Qd is quantity demanded per month, p the price of a haircut, and Y the average monthly income in the town. The supply function for men’s haircuts is QS=100+20p−20w, where Qs is the quantity supplied and w the average hourly wage of barbers. If Y=5000 and w=10, use Excel to calculate quantity demanded and quantity supplied for p=5,10,15,20,25,30. Calculate the excess demand for each price (Note that an excess supply is negative excess demand.) Determine the equilibrium price and quantity. Use Excels charting tool to draw the demand and supply curves. Assume that Y increases to 6875 and and w increases to 15. Use Excel to recalculate quantity demanded for p=5,10,15,20,25,30. Determine the new equilibrium price and quantity. Use Excel to draw the new demand and supply curves. how can you explain the change in equilibrium?

In 2004 the Pandora made a rights issue at $5 a share of one new share for every four shares held. Before the issue there were 100 million shares outstanding and the share price was $6. For questions (a) to (c) assume that all rights were exercised.

(a) What was the total amount of new money raised?

(b) What was the value of the right to buy one new share?

(c) What was the prospective stock price after the issue?

(d) How far could the stock price after the issue fall before shareholders would be unwilling to take up their rights?

(e) Suppose that the rights issue is at $4 rather than $5 per share. How many new shares would it have needed to sell to raise the same sum of money? How do your answers to (b) and (d) change? Are the shareholders any better or worse off with the $4 exercise price?

7.29 The mean preparation fee H&R Block charged retail customers last year was $183 (The Wall Street Journal, March 7, 2012). Use this price as the population mean and assume the population standard deviation of preparation fees is $50. Use Excel to compute your answers.

Can you please help using excel I'm not understanding how to make this work with excel.

a. What is the probability that the mean price for a sample of 30 H&R Block retail customers is within $8 of the population mean?

b. What is the probability that the mean price for a sample of 50 H&R Block retail customers is within $8 of the population mean?

c. What is the probability that the mean price for a sample of 100 H&R Block retail customers is within $8 of the population mean?

d. What is the minimum samples size if you want to have at least a .95 probability that the sample mean is within $8 of the population mean?

The mean preparation fee H&R Block charged retail customers last year was $183 (the Wall Street Journal, March 7, 2012). Use this price as the population mean and assume the population standard deviation of preparation fees is $50.

1. What is the probability that the mean price for a sample of 30 H&R Block retail

   customers is within $8 of the population mean?

2. What is the probability that the mean price for a sample of 50 H&R Block retail

   customers is within $8 of the population mean?

3. What is the probability that the mean price for a sample of 100 H&R Block retail

   customers is within $8 of the population mean?

4. Which, if any, of the sample sizes in parts (a), (b), and (c) would you recommend to

   have at least a .95 probability that the sample mean is within $8 of the population mean?

i need DISTRIBUTION, MEAN, STANDARD DEVIATION, of x-bar for each question 1-3 and  175<xbar<191 please.

The inverse market demand curve for bean sprouts is given by P(y ) = 100−2y , and the total cost function for any firm in the industry is given by TC(y)=4y. a. If the bean-sprout industry were perfectly competitive, what would be the industry output and price? b. Suppose that two Cournot firms operate in the market, and each firm has the above total cost function. Find the reaction functions of the two firms. c. Find the Cournot equilibrium output and price. d. For the Cournot case, draw the two reaction curves and indicate the equilibrium point on the graph. e. If the two firms decide to collude, what will be the industry output and price? f. Suppose one firm acts as a Stackleberg leader and the other firm behaves as a follower. Write down the maximization problem for the leader. g. What are the levels of output of the leader and follower? What is the industry price? Compare them to the Cournot case.

1. Two types of customers make up the market for Armoyas. There are 80 type A customers, each of whom is willing to pay up to $10 for an Armoya. There are 40 type B customers, each willing to pay up to $8 for an Armoya. No customer wishes to buy more than a single Armoya. The monopolist cannot differentiate between the types of customer. The average and marginal cost of production is constant at $6/Armoya.
   
2. 1. What is the selling price of the good, and how much profit does the monopolist make?
      
   2. The monopolist is offered the opportunity to advertise Armoyas at a cost of $80. The advertisement is predicted to attract another 100 type B customers. Will the advertisement be placed? What is the selling price of the good, and how much profit does the monopolist make?
      
   3. Suppose the advertisement attracts no new customers, but raises the price all existing customers are willing to pay by $1. Will the advertisement be placed? What is the selling price of the good, and how much profit does the monopolist make?
