This project should be completed using Excel (with formulas and linked data). Below are the deliverables: 1. Prepare a Multi-Step Income Statement for the year ended 2018. This statement should be flexibly designed (formulas in cells). To the right of your dollars in this statement, show common-sized percentages based on sales (vertical analysis). 2. Show journal entries, adjusting entries and closing entries for the below additional information…none of the journal entries for 2018 have been posted to the ledger. 3. Prepare a Statement of Retained Earnings for the year ended 2018. This statement should be flexibly designed. 4. Prepare a Classified Balance Sheet dated Dec. 31, 2018. Again, a flexible design is required so any changes will automatically update the balance sheet. 5. Prepare a Statement of Cash Flows using the indirect method for the year ended 2018. The Statement of Cash Flows (operating section) should automatically change when assumptions are changed. Your Name, Inc. Balance Sheet 12/31/2017 Current Assets Cash $18,000 Marketable Securities (Short-term) 2,000 Accounts Receivable 14,000 Allowance for Bad Debt (2,000) Inventory 15,000 Prepaid Insurance 5,000 Total Current Assets $52,000 Property, Plant, and Equipment Land $30,000 Building 150,000 Accumulated Dep. – Building (45,000) Equipment 100,000 Accumulated Dep. - Equipment (20,000) Total PPE $215,000 Total Assets $267,000 Current Liabilities Accounts Payable $9,000 Unearned Revenue 3,000 Income Taxes Payable 3,000 Total Current Liabilities $15,000 Long-term Liabilities Bonds, 10%, due in 2021 $100,000 Equity Common Stock $ 50,000 (100,000 authorized, 50,000 issued) cont. Additional Pd.-in Capital 80,000 Retained Earnings not given (must be calc.) Total Equity $152,000 Total Liabilities & Equity $267,000 Additional Information (for all entries): 1. Sales for 2018 are $250,000. All sales are on credit. 2. Gross Margin/Profit ratio is 40 percent 3. Accounts Receivable: i. $180,000 of the accounts receivable is paid by the end of the year (the remaining balance remains on the balance sheet). ii. $3,000 of A/R is written off during the year. iii. 5% of Accounts Receivable (after write-off and collections) is considered to be uncollectible. 4. Inventory: i. Inventory purchases is $175,000, all on credit (the periodic method is used). ii. All accounts payable is from inventory purchases; all but $12,000 of inventory purchased is paid by the end of the year. 5. Additional equipment is purchased on 4/1/18 for $20,000 cash. All equipment when new, including the new purchase, has/had a five year life, no salvage value, and is depreciated using the straight-line method. 6. The building depreciates at $5,000 per year. 7. Half of the marketable securities were sold for $1,300. The FMV of the other half of the securities is also $1,300 and an adjustment to FMV is required. 8. Salaries are $2,100 per month (12 months of salaries expense must be booked). It is expected that one-half month will be owed on 12/31/18 because of when payday falls (therefore, 11.5 months of salaries have been paid and ½ month is still owed to the employees at year end). 9. $60,000 in cash is borrowed on 10/31/18 by issuing a Note Payable. Interest is 8% per year. 10. The bonds were sold at face value last December and pay interest on Dec. 31, 2018. 11. 10,000 additional shares of stock were sold for $4 a share (for EPS purposes, assume these shares were outstanding all year). 12. Insurance costing $20,000 was purchased on 7/1/18 (the same time in which the policy purchased in 2017 expired. The new policy was for 12 months). 13. On Dec. 31, 2018, 1000 shares of stock are repurchased from the market at $2.80/share (treasury stock). 14. The tax rate is 30 percent. Income taxes for the current year are due and therefore paid during the first two months of the next year (you will have to complete an entry to pay the 2017 taxes, however the 2018 taxes will not be paid until the end of January 2019). 15. Dividends of $4,000 were paid during 2018. 16. The unearned revenue has been earned during the year (classified as other revenue on the multi-step income stmt.). Required Labeled Sheets in Excel (all statements should be for 2018): 1. Data Sheet (the ending balances from 2017 – provided on the 2017 balance sheet) 2. Entries: Basic and Adjusting (you do not have to separate these entries) 3. Adjusted Trial Balance for 2018 (includes the posted amounts of all entries and adjusting entries) 4. Multi-step Income Statement 5. Retained Earnings Statement 6. Classified Balance Sheet 7. Cash Flow Statement (using the indirect method) 8. Post-Close Trial Balance for 2018 (include your closing entries above your post close trial balance)

Basic entries and adjusting entries and Multi-step Income Statement has been answered. Will require solutions for remaining 6 questions that will be Q 3, 5, 6, 7 and 8.

Project 3 instructions

Based on Larson & Farber: sections 5.2–5.3

Using the provided data. Assume that the closing prices of the stock form a normally distributed data set. This means that you need to use Excel to find the mean and standard deviation. Then, use those numbers and the methods you learned in sections 5.2–5.3 of the course textbook for normal distributions to answer the questions. Do NOT count the number of data points.

Complete this portion of the assignment within a single Excel file. Show your work or explain how you obtained each of your answers. Answers with no work and no explanation will receive no credit.

1) If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than the mean for that year? Hint: You do not want to calculate the mean to answer this one. The probability would be the same for any normal distribution. (5 points)

2) If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at more than $825? (5 points)

3a) If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed within $50 of the mean for that year? (5 points)

3b) If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than $700 per share. (5 points)

3c) At what prices would Google have to close in order for it to be considered statistically unusual? You will have a low and high value. Use the definition of unusual from the course textbook that is measured as a number of standard deviations. (5 points)

4) What are Quartile 1, Quartile 2, and Quartile 3 in this data set? Use Excel to find these values. This is the only question that you must answer without using anything about the normal distribution. (5 points)

5) Is the normality assumption that was made at the beginning valid? Why or why not? Hint: Does this distribution have the properties of a normal distribution as described in the course textbook? Real data sets are never perfect, however, it should be close. One option would be to construct a histogram like you did in Project 1 to see if it has the right shape. Something in the range of 10 to 12 classes is a good number. (5 points)

There are also 5 points for miscellaneous items like correct date range, correct mean, correct SD, etc.

The schema for the Academics database is as follows. Understanding this schema is necessary to answer the questions in Part B.

DEPARTMENT(deptnum, descrip, instname, deptname, state, postcode) 
ACADEMIC(acnum, deptnum*, famname, givename, initials, title) 
PAPER(panum, title) 
AUTHOR(panum*, acnum*) 
FIELD(fieldnum, id, title) 
INTEREST(fieldnum*, acnum*, descrip) 

The semantics of most attributes are self-explanatory. For each relation, the primary key is underlined and any foreign keys are denoted by an asterisk (*). Some additional information for relations is given below:

• DEPARTMENT: Each academic department (deptnum) belongs to an institution (instname).  
• ACADEMIC: Each academic (acnum) belongs to one department (deptnum).  

• AUTHOR: A paper (panum) may be written by more than one academic (acnum).  
• FIELD: The relation describes research areas, where id is a classification code like B.1.1.  
• INTEREST: The relation describes that an academic may have research interests in several fields (fieldnum), and provide description (descrip) of his/her research.

Question1 SQL

calculate the number of academics that have more than 10 papers?

Question 2 SQL

find the departments where at most 10 academics have more than 2 research fields, and display in alphabetical order the names of institutions and names of departments?

You are hired to design a database for a fitness center. As the fitness center is expanding with more than one branch, they want to create a database to keep track of its customers, facilities and employees. Each branch has a unique id and address (building number, street, district, and city). A branch may have more than one facility (e.g. swimming pool, spa, etc.). Each facility must belong to only one branch, and the information for a facility is name and fees. In addition, each fitness branch offers different classes (such as Yoga, Pilates, Zumba, etc.). All classes should be led by at most one trainer, who is an employee.

Employees must work at one and only one branch. Each employee has an id, name, address (building number, street, district, and city) and can have multiple phone numbers. An employee can only be an admin, managing the facility or working as a clerk, or a trainer. An employee cannot be a trainer and an admin because the trainer id compensated an hourly wage while an admin staff paid a monthly salary. Trainers can train individual customers at different time sessions.

A customer must register at one branch. Each customer has a membership number, name (stored as first name and last name), email, and only one phone number. A customer can join more than one class or uses any number of facilities. A customer may also decide to be trained by at most one personal trainer.


Given the above description: 1. Draw an ERD for the database, identifying the following: a. All the entities, attributes and relationships b. Primary key and (discriminator in weak entity, if any). Don’t forget each entity has to have PK. c. Participation and cardinality constraints. (Explain your choices for two constraints- i.e. identify the words the guided your decision) d. Specialization and completeness constraints (if there is an ISA relationship).

2. Write a schema for two entities and two relationships of your choice. Remember, sometimes a relationship is better not be represented in a separate schema; if this is the case with your chosen relationship explain what you will do.

Consider the design of a database for a web site of a web site of videos that teach people how to do things by yourself, such as house renovation. We will call videos as DIY videos. First, all registered users can post DIY questions, such as “how to paint a wall”. Each DIY question is identified by a question ID, the question itself, and a list of tags (each tag is a lower case word) to annotate the question, and the date the question is posted,. For example, for the question “how to paint a wall”, we can add the tags “wall, paint, roller, brush”. A registered user can also post a DIY video (from the existing video website) to an existing DIY question. Each video is identified by a unique URL (use the URL when you click the share button at the video website page, a title and a description of the video, the date on which the video is posted to your database system. A registered user can search for videos by typing a question (ideally, support fuzzy search since a user might not be able to type the exact phrase in a question), all relevant video links will be returned as a list so that a user can click any video link in the result list to play that video. Each registered user is identified by a unique username, which must be an email, a password, a first name, a last name, the gender, and his/her birthday. A registered user can give at most one review for each video, but on a particular day, the user can post at most three videos. The review given by a user has a score of {“Poor”, “Fair”, “Good”, “Excellent”} and then a short remark. A user can also modify an existing review as well as deleting an existing review. Each user has a private favorite list of DIY videos(called my favorite DIYs). Each user can insert or delete a DIY video from that favorite list. When each video is shown, the DIY question will also be shown beside the title of the video, so that a user can click it to see other videos for this DIY question. While a video is on display, there is a button under the video called “Add to my favorite DIYs” so that a user can easily add this video to his/her favorite DIYs. The system has a distinguished user called “root” whose username is root (this is the only username that is not an email).

- Draw an E-R diagram for the system, in particular, use arrows or thick lines to represent constraints appropriately. Write down your assumptions and justifications briefly and clearly.

- Translate the above E-R diagram into a relational model, i.e., write a set of CREATE TABLE statements. In particular, specify primary key, foreign key and other constraints whenever possible.
