Ross Co., Westerfield, Inc., and Jordan Company announced a new agreement to market their respective products in China on July 18, February 12, and October 7, respectively. Given the information below, calculate the cumulative abnormal return (CAR) for these stocks as a group. Assume all companies have an expected return equal to the market return. (A negative value should be indicated by a minus sign. Leave no cells blank - be certain to enter "0" wherever required. Do not round intermediate calculations. Round your answers to 1 decimal place.)

Use data below to complete

Table 1.18 Frequency of Number of Movies Viewed

Table 1.19 Frequency of Number of Movies Viewed

1. Using the tables, find the percent of data that is at most two. Which table did you use and why?
2. Using the tables, find the percent of data that is at most three. Which table did you use and why?
3. Using the tables, find the percent of data that is more than two. Which table did you use and why?
4. Using the tables, find the percent of data that is more than three. Which table did you use and why?

Discussion Questions

1. Is one of the tables “more correct” than the other? Why or why not?
2. In general, how could you group the data differently? Are there any advantages to either way of grouping the data?
3. Why did you switch between tables, if you did, when answering the question above?

Let x, y ∈ Z. Prove that x ≡ y + 1 (mod 2) if and only if x ≡ y + 1 (mod 4) or x ≡ y + 3 (mod 4)

Directions:

Using a vector of integers that you define.

Write a C++ program to run a menu driven program with the following choices:

1) Display the ages
2) Add an age
3) Display the average age
4) Display the youngest age
5) Display the number of students who can vote
6) Remove all students less than a given age
7) Quit

Make sure your program conforms to the following requirements:

1. Write a function called getValidAge that allows a user to enter in an integer and loops until a valid number that is >= 0 and < 120 is entered. It returns the valid age.

2. Write a function called displayAges that takes in a vector of integers as a parameter and displays the ages in the format in the sample run below.

3. Write a function called AddAge that takes in a vector of integers by reference as a parameter, asks the user to input a valid age, and adds it to the vector of integers .

4. Write a function called getAverageAge that takes in a vector of integers as a parameter, computes, and returns the average age.

5. Write a function called getYoungestAge that takes in a vector of integers as a parameter, computes, and returns the youngest age.

6. Write a function called getNumStudentsVote that takes in a vector of integers as a parameter, computes, and returns the number of ages in the vector that are >= 18. (15 points).

7. Write a function called RemoveStudentsLessThanSelectedAge that takes in a vector of integers as a parameter, asks the user for an age, creates a new vector of integers that only contains the ages in the parameter vector which are >= the age selected by the user and returns the new vector.

8. Add comments wherever necessary.

NOTE: You must take care of the case when the vector is empty and an operation is being performed on it. In such cases the program should display a 0 for the given result.

General Requirements:

1. Please make sure that you're conforming to specifications (program name, print statements, expected inputs and outputs etc.). Not doing so will result in a loss of points. This is especially important for prompts.

2. If we have listed a specification and allocated point for it, you will lose points if that particular item is missing from your code, even if it is trivial.

3. No global variables (variables outside of main() ) unless they are constants.

4. All input and output must be done with streams, using the library iostream

5. You may only use the iostream, iomanip, and vector libraries. Including unnecessary libraries will result in a loss of points.

6. NO C style printing is permitted. (Aka, don't use printf). Use cout if you need to print to the screen.

7. When you write source code, it should be readable and well-documented (comments).

The market consists of 2 firms. The firms produce the same product. Firm 1 with $1 per-unit cost (C₁(q₁)=1q₁ ). Firm 2 with $1 per-unit cost (C₂(q₂)=1q₂ ). Firm 1 can set its price to 2 or 3 or 4 $. Firm 2 can set its price to 2 or 3 or 4 $. The industry's demand function is Q= 10 – P (P-price, Q- total quantities). The firms choose their quantities simultaneously.

1a) Find Firm 1 optimal price P1=?

1b) Find Firm 2 optimal optimal price   p2=?.

1c) Determine the equilibrium quantity? (Q=?)

1d) Firm 1 will earn? (pi1=?)

1e) Firm 2 will earn? (pi2=?)

The market consists of 2 firms. The firms produce the same product. Firm 1 with $1 per-unit cost (C₁(q₁)=1q₁). Firm 2 with $1 per-unit cost (C₂(q₂)=1q₂). Firm 1 can produce 2 or 4 or 6 units. Firm 2 can produce 2 or 4 or 6 units. The industry's demand function is Q = 50 - P (P=price, Q=total quantities). The firms choose their quantities simultaneously.

1a) Find Firm 1's optimal production levels. q1=?

1b) Find Firm 2's optimal production levels. q2=?

1c) Determine the equilibrium price. p=?

1d) Firm 1 will earn how much?

1e) Firm 2 will earn how much?

Consider the data sheet below that tracks employee hours worked over four days:

   Day 1 Day 2 Day 3 Day 4
Employee 1 5 8 6 2
Employee 2 2 0 8 6
Employee 3 6 4 9 5
Employee 4    7 8 8 4
Employee 5   3 6 2 8
Employee 6   9 5 1 7

Based on the above information, write a Java program that performs the following tasks:

Task 1) Recreate the matrix as a two-dimensional array by hardcoding values (User input is not needed)
Task 2) Calculate and print the total number of hours worked across all employees
Task 3) Find the employee who worked the most number of hours (Hint: Total all of the columns in each row. Keep track of the "largest" row and the employee associated to that row.
Task 4) Find the employee who worked the least number of hours (Hint: Total all of the columns in each row. Keep track of the "smallest" row and the employee associated to that row.

Example run:

The total number of hours worked across all employees: 129
The employee that worked the most number of hours was Employee 4 working 27 hours
The employee that worked the least number of hours was Employee 2 working 16 hours

Note: For output, use the JOptionPane class.
