1. In a highlighted box, explain how each hypothesis test contributes to the central question of which major would give the better ROI. Why do we need hypothesis testing? Isn't it enough to look at the sample of 20 schools and look at those numbers? What exactly does hypothesis testing do that looking at the numbers in the sample and saying "one is higher than the other" cannot do? This answer is critical to your final project. It demonstrates that you understand why you just can't look at the mean, median, and mode of the spreadsheet and "call it a day
2. . For Business versus Engineering majors conduct a full, two-sample, full hypothesis test at the 5% significance level (assume the variances are not equal):The average ’30-Year ROI’ for Business majors is less than for Engineering Majors.
   • The mean ‘Cost’ for a college is $160,000.
3. For each of the 2 majors, conduct a full hypothesis test at the 10% significance level:

1. Which of the environmental policy options discussed during class would you recommend if a hypothetical society were facing the environmental problems listed below? In each case, briefly explain the justification(s) for your choice:

1. Pollution from an estuary from multiple irrigation runoffs;
2. Air pollution of a major metropolitan area;
3. The clean up of a toxic waste dump;
4. Damage to lakes, streams, forests and soil resulting from acid rain;
5. A threat to human health due to stratospheric ozone depletion;
6. Marine pollution;
7. A well-founded fear for gradual extinction of endangered species, for example, my personal favorite, the blobby fish (shown above just in case you were sleeping soundly each night)

Develop a simple MIS (Management Information System) for High School Student that consists of a simple database (a text file). The system manages to dynamically input record/data into the database. The data from the database can be sorted, searched and updated. User also should be able to add new records/data, remove any data and etc.

• The system that will be developed must use a linked list structure.
• Use any sorting techniques to sort your data.
• Use any searching techniques to search for a data.
• Develop a user friendly and efficient system
• Use only notepad (a text file) as your simple database.
• must use C++ and text file only for the database.

Example of the user interface for a Students Management System.

Main Menu

Welcome to A* High School Students Management System.

Please select your choice:

1. Adding a new student record
2. Updating an existing student record
3. Search a student record.
4. View students record.
5. Remove a student record.
6. Exit.

Your choice: 4

Menu view students record

1. View a student record
2. View all students record

Your choice: 2

Guildline:

1. When updating the existing data, you should prompt a user to enter the ID. Once the ID is ready, you have to find the ID from your file/database. Retrieve data of the database. Then you can update the data such as the new address and phone number. Of course you cannot edit the ID, name and DOB.
2. When searching for a data, you should display the result. For example, if the data is found, the details of the data should be displayed.
3. Add function should able the new record being added into the existing database. For example, before this you have 4 records in your database, after adding a record, your file should have 5 data.
4. To view data of your record, the result should be sorted, just like the example given.

Learning Objective: Explain why different people are motivated by different things.
Summary: The goal of this exercise is to give students practice aligning individual and organizational goals, and thinking like a manager in managing employee motivation. Imagine that you are the management team of a new retail clothing store named Threads. Your company’s business strategy is to provide high-quality customer service and to provide high-quality products. You are not the cheapest store in town, but you expect your employees to create a service-oriented atmosphere that customers will be willing to pay a little extra for. You recognize that your sales staff will be essential to your store’s success, and you want to create a system that motivates them to help create a competitive advantage for your business. Because this is the first store you have opened, you have the opportunity to decide how to best motivate your staff. Market-competitive starting salaries have already been established, but you have decided to allocate 10 percent of the stores’ profits to use to motivate your sales staff in any way you see fit.
Question to be answer

What goals would you set for your sales staff? (750 words)

You suspect that townsfolk near Gloomsville are getting cancer because of a new toxic waste dump built in town. So, suspecting this is in the water, you look at cancer rates up to 20 miles downstream from the dump site. Is cancer evenly distributed along those 20 miles? The data to answer this question are in the table above.

I will have to solve this using Excel. Specifically what should I do? What functions could I use? For the question, I have to

1. A null and alternative hypothesis stated, as appropriate and for each hypothesis tested. may involve several hypothesis tests.

2. Choose the most appropriate test. Explain how you have met the assumptions of the test or why the test is robust to violations of the assumptions.

3. State explicitly what test(s) you are using.

4. If you fail to reject the null hypothesis, calculate the power of the test.

Answer 2 of the following questions and relate your answer with other students’ answers: 1. If your incomes increases by 20 percent, how much would your quantity demanded change per month on average? Estimate your income elasticity and explain your answer. 2. What is the cross-elasticity of supply of one of the goods or services that your company provides? Why? How does your answer relate with another student answer? 3. Gridlock in Toronto already costs the region $6 billion a year, with average commute times of 80 minutes, among the highest in North America. By 2031, commute times will increase by 27 minutes. Civic leaders are looking at the options: road tolls, a regional gas tax, and parking levies. Source: Toronto Star, June 24, 2011 With road tolls, a regional gas tax, and parking levies would Toronto roads become less congested? If the new charges cut commute times, would the Toronto road system be more efficient? Explain your answers. 4. Explain a negative externality that you have experienced or that your town/region has experienced. How did you address it? What was the role of the government in it? And the role of private organizations?

C Programming Language:

For this lab, you are going to create two programs. The first program (named AsciiToBinary) will read data from an ASCII file and save the data to a new file in a binary format. The second program (named BinaryToAscii) will read data from a binary file and save the data to a new file in ASCII format.

Specifications:

Both programs will obtain the filenames to be read and written from command line parameters. For example:

- bash$ AsciiToBinary ascii_in binary_out
- bash$ BinaryToAscii binary_in ascii_out

The data contained in the ASCII file (both reading from and writing to) will be 10 floating point numbers, 10 lines of text, and 10 signed integers. There will be only one data item per line, and each line of text will contain no more than 40 characters (including '\n' and the NULL terminator).

The data contained in the binary file (both reading from and writing to) will be 10 floating point numbers (of type double), 400 characters, 10 signed integers. You may find it helpful to think of the 400 characters as 10 lines of 40 characters each. When writing the floating point values to the ASCII output file, write them to four decimal places.

Sample ASCII and binary format files are provided. The data in the two files correspond to each other. There will be no blank lines found in either file.

The specific method that you use to read and write the data is up to you. You may wish to read all the data from the input file before writing to the output file, or you may wish to write each data element as it is read.

Be sure to close both files (input and output) before exiting the program.

Testing:

Besides testing your code with your usual methods, you should also test your programs by reading an ASCII file, converting it to binary, then reading the binary file and converting it to ASCII. The new ASCII file should match exactly with the original ASCII file.

Many prestigious universities have a system called a “Legacy Preference System” which is used to decide which applicants should be accepted to the university. If an applicant’s parent is an alumnus of the university, the applicant will be admitted with lower GPA and SAT scores than if the parent is not an alumnus. (There is currently a lot of discussion about the fairness of this system, but universities get a lot of money from their alumni so they are unwilling to change it!!)

Your assignment for MP2 is to implement a computerized system like this for a very small prestigious university. The university has two schools, Liberal Arts and Music, each with their own criteria for accepting students. Your program must read in certain information about an applicant and print a message saying whether the applicant should be accepted or not.

The criteria for acceptance are:

Liberal Arts

1. No more than 5 people can be accepted.
2. If a parent is an alumnus, the GPA must be at least 3.0, but if no parents are alumni the GPA must be at least 3.5.
3. If a parent is an alumnus, the combined SAT score must be at least 1000, but if no parents are alumni the SAT must be at least 1200.

Music – no preferences for alumni here.

1. No more than 3 people can be accepted.
2. Math and verbal SAT’s must be at least 500 each.

Your program must accept as input the school the student is applying to (L or M), their high school grade point average, their math SAT score, their verbal SAT score and whether or not either parent is an alumnus (Y or N). The program must process several applicants, echoing the data for each applicant and printing a message indicating if the student was accepted to the school they were applying to. If they were not accepted, the message should indicate why. This message only has to indicate one reason for failure in cases of multiple disqualifications. Acceptances are to be made in the order received so that if a school is full, a later applicant cannot be accepted even if they happen to have better qualifications than an earlier one. You do NOT have to check for bad data coming from the file – assume that it is in the required format and has appropriate values.

The data file is arranged with the information for each applicant on a separate line. Your program must process the data until the end of file is reached, at which time the program must print out the total number of applicants and the number of acceptances to each school. The data file should be created by you. Create the file and store it in the same project folder as your program. Please turn in a hard copy of this file along with your program and output.

SUGGESTION You should design, compile, run and debug your program in stages. You might start by testing if your program can just read and echo the data file. After this is working accurately move on to identifying the school the person is applying to, then continue to add more of the details. Remember to use good style with consistent indentation, plenty of comments, good variable names etc. and don't forget to echo the data as it is read. The output must be clear and readable with appropriate string constants and spacing. Here is an example of the input data file:

L 4.0 600 650 N
M 3.9 610 520 N
L 3.8 590 600 N
…
Sample output from the first few lines of the example data file follows:

Acceptance to College by (your name)

Applicant #: 1
School = L GPA = 4.0 math = 600 verbal = 650 alumnus = N
Applying to Liberal Arts
Accepted to Liberal Arts!!!
*******************************
Applicant #: 2
School = M GPA = 3.9 math = 610 verbal = 520 alumnus = N
Applying to Music
Accepted to Music!!
*******************************
Applicant #: 3
School = L GPA = 3.8 math = 590 verbal = 600 alumnus = N
Applying to Liberal Arts
Rejected - SAT is too low
*******************************
…
There were xx applicants in the file
There were xx acceptances to Liberal Arts
There were xx acceptances to Music
Press any key to continue

Use the following input file for your program, notice there is exactly 14 applicants, make sure you display the counts at the end of your output as in the sample above.

mp2accept.txt

L 4.0 600 650 N
M 3.9 610 520 N
L 3.8 590 600 N
L 3.0 600 600 Y
L 3.4 600 600 N
L 3.0 500 490 Y
L 2.9 500 500 Y
M 3.5 500 490 Y
M 3.9 490 600 Y
L 3.5 700 500 N
L 3.1 600 400 Y
L 3.0 490 510 Y
L 4.0 800 800 Y
M 3.2 500 500 N
