Exercise 6.1.1 : Suppose there are 100 items, numbered 1 to 100, and also 100 baskets, also numbered 1 to 100. Item i is in basket b if and only if i divides b with no remainder. Thus, item 1 is in all the baskets, item 2 is in all fifty of the even-numbered baskets, and so on. Basket 12 consists of items {1, 2, 3, 4, 6, 12}, since these are all the integers that divide 12. Answer the following questions:

(a) If the support threshold is 5, which items are frequent?
! (b) If the support threshold is 5, which pairs of items are frequent?

! (c) What is the sum of the sizes of all the baskets?

PS： I know the answer of a) which are 1, 2, 3, 4 ... 18, 19, 20. But how to get the answers of b) and c) please show the steps and the explanation. Thank you.

Randomly generate 0, 1, or 2 in a 100 by 100 2d array.
For each entry in the 2d array, count the number of 0’s and 1’s in the surrounding entries.
Save the result in two 2d arrays: one for the number of 0’s, one for the number of 1’s.
For example:
0   0   1
2   1   0
0   0   0

The number of 0’s for a[0][0] is 1; the number of 1’s for a[0][0] is 1;
The number of 0’s for a[0][1] is 2; the number of 1’s for a[0][1] is 2;
The number of 0’s for a[0][2] is 2; the number of 1’s for a[0][2] is 1;
The number of 0’s for a[1][0] is 4; the number of 1’s for a[1][0] is 1;
The number of 0’s for a[1][1] is 6; the number of 1’s for a[1][1] is 1;
The number of 0’s for a[1][2] is 3; the number of 1’s for a[1][2] is 2;
The number of 0’s for a[2][0] is 1; the number of 1’s for a[2][0] is 1;
The number of 0’s for a[2][1] is 3; the number of 1’s for a[2][1] is 1;
The number of 0’s for a[2][2] is 2; the number of 1’s for a[2][2] is 1;

Suppose we have the following table that summarises the domestic demand and supply schedule for Canadian crude oil

If Canada does not trade with the rest of the world, what is the equilibrium price ___ ? (Answer is 101, how did they get that?)

What is the equilibrium quantity _____? (Answer is 13, how did they get that?)

Suppose the world price is 102, and Canada opens up free trade, what is the new equilibrium price in Canada _____? (Answer is 102, how did they get that?)

Canada will have ____ units in its domestic market? (Answer is 2, how did they get that?)

Suppose the world price is 102 and Canada imposes a tariff of 4 then Canada exports ____ units? (Answer is 10, how did they get that?)

Question 2. Consider the market for burritos in Vancouver, blessed with thousands of students and dozens of small burritos stands. The demand and supply schedules are shown in the table.

1. Graph the demand and supply curves. What is the free -market equilibrium in this market?

Answer:

2. What is the total economic surplus in this market in the free-market equilibrium? What area in your diagram represents this economic surplus?

Answer:

3. Suppose the local government, out of concern for the students' welfare, enforces a price ceiling on burritos at the price of $1.50. Show in your diagram the effect on price and quantity exchanged.

Answer:

4. Are students better off as a result of this policy? Explain.

Answer:

5. What happens to overall economic surplus in this marker as a result of the price ceiling? Show this in the diagram.

Answer:

The yield to maturity on 1-year zero-coupon bonds is currently 5.5%; the YTM on 2-year zeros is 6.5%. The Treasury plans to issue a 2-year maturity coupon bond, paying coupons once per year with a coupon rate of 7.5%. The face value of the bond is $100.

a. At what price will the bond sell? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

Price:

b. What will the yield to maturity on the bond be? (Do not round intermediate calculations. Round your answer to 3 decimal places.)

Yield to Maturity:

c. If the expectations theory of the yield curve is correct, what is the market expectation of the price that the bond will sell for next year? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

Price:

d. Recalculate your answer to (c) if you believe in the liquidity preference theory and you believe that the liquidity premium is 1.5%. (Do not round intermediate calculations. Round your answer to 2 decimal places.)

1. A candy bar manufacturer is interested in estimating sales using price of the candy bar in different cities. To do this the manufacturer randomly selected 7 small cities and offered the candy at different price.  Using candy bar sales as dependent variable, the manufacturer will conduct simple regression using the data below:

Using above information:

1. The price of candy in a city is $3.50. What is the sale estimate for the city?
2. Compute the standard error of the estimate
3. Compute the coefficient of determination r² and interpret it meaning in this problem
4. At a significance level of .01 can you conclude that the Price is a good predictor of the Sales.

The yield to maturity on 1-year zero-coupon bonds is currently 7%; the YTM on 2-year zeros is 8%. The Treasury plans to issue a 2-year maturity coupon bond, paying coupons once per year with a coupon rate of 9%. The face value of the bond is $100.

a. At what price will the bond sell? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

b. What will the yield to maturity on the bond be? (Do not round intermediate calculations. Round your answer to 3 decimal places.)

c. If the expectations theory of the yield curve is correct, what is the market expectation of the price that the bond will sell for next year? (Do not round intermediate calculations. Round your answer to 2 decimal places.)

d. Recalculate your answer to (c) if you believe in the liquidity preference theory and you believe that the liquidity premium is 1%. (Do not round intermediate calculations. Round your answer to 2 decimal places.)

Last year Minden Company introduced a new product and sold 25,900 units of it at a price of $100 per unit. The product's variable expenses are $70 per unit and its fixed expenses are $836,100 per year.

Required:

1. What was this product's net operating income (loss) last year?

2. What is the product's break-even point in unit sales and dollar sales?

3. Assume the company has conducted a marketing study that estimates it can increase annual sales of this product by 5,000 units for each $2 reduction in its selling price. If the company will only consider price reductions in increments of $2 (e.g., $68, $66, etc.), what is the maximum annual profit that it can earn on this product? What sales volume and selling price per unit generate the maximum profit?

4. What would be the break-even point in unit sales and in dollar sales using the selling price that you determined in requirement 3?
