From a management perspective why do you think budgets are so important AND give an example, that relates specifically to your major, of how you will use budgets in your field. Do not forget APA format on your sources and in-text citations.

10. What are some concerns you might have about owning stocks and 10-year government bonds over the next 12 months? Support your outlook and concerns with citations from primary sources such as economist’s reports or investor surveys.

Question 1: In the NCBI database, retrieve the nucleotide sequences NG011676. Report:

1. Gene name, database name.

2. Number of exons and its position (the start and the end of each exon).

3. The start and the end of coding region (CDS)

4. Accession number of protein from this gene and the length of polypeptide.

Question 2: Use NG011676 to run GenScan. Report the results and compare the results with information of this gene from Question 1.
Question 3: Use NG011676 to run FGENESH with selecting of Homo sapiens as organism specific gene-finding parameters. Report the results and compare the results with information of this gene from Question 1.

Consider the following database schema for a BOOKSTORE database:

• Books (bookid, title, author, year)
• Customers (customerid, name, email)
• Purchases (customerid, bookid, year)
• Reviews (customerid, bookid, rating)
• Pricing (bookid, format, price)

The Books relation stores information about books sold by the bookstore. Note that bookid is the primary key. An example tuple is as follows:

(105, 'JAVA PROGRAMMING', 'JOHN DOE', 2001)

The Customers relation stores information about the customers of the bookstore. Note that customerid is the primary key. An example tuple is as follows:

(210, 'JOHN SMITH', '[email protected]')

The Purchases relation stores information about the customer purchases of books. Note that customerid and bookid form the primary key. An example tuple is as follows:

(210, 105, 2002), indicating that 'JOHN SMITH' with customerid 210 purchased the 'JAVA PROGRAMMING' book with bookid 105 in the year 2002.

The Reviews relation stores information about the customer reviews/ratings of the books. The ratings field refers to the number of "stars" given to the book. Note that customerid and bookid form the primary key. An example tuple is as follows:

(210, 105, 3), indicating that 'JOHN SMITH' with customerid 210 gave a 3-star rating to the 'JAVA PROGRAMMING' book with bookid 105.

The Pricing relation stores information about the price of the various books sold by the bookstore. Note that the same book can be available in multiple formats at possibly different prices. The price field refers to the number of dollars. For instance a $25 purchase will have a price field of 25. Note that the bookid and format fields form the primary key for the relation. An example tuple is as follows:

(105, 'AUDIO', 25), indicating that the 'JAVA PROGRAMMING' book with bookid 105 is available in the audio format for $25.

Given the above schema, write queries for the following:

1. Find books (show their titles) written by 'EDMUND MORGAN' since year 1990.
2. Find books (show their titles, authors and prices) that are on 'CIVIL WAR' (i.e., the title field contains 'CIVIL WAR'), available in 'AUDIO' format.
3. For each year, 'JOHN CHAMBERS' purchased at least one book, find the number of books purchased. That is, the output should be a set of tuples, each indicating a year and the number of books purchased by 'JOHN CHAMBERS' in that year.
4. Find customers (show their names and email addresses) who purchased more than one book in year 2003.
5. Find the ratings information (show titles, authors and average ratings) for books on 'CIVIL WAR' (i.e., title contains 'CIVIL WAR').

mySQL database question.. I have a database that has the following tables:

User (Id, Name, Gender) Primary key = Id

Friends (Id1, Id2, Startdate) Primary key = (Id1, Id2) Foreign keys are also Id1, Id2 pointing to User(Id)

Comments (CommentId, Poster, Recipient, Text, PostDate) Primary key = (CommentId) Foreign Keys are Poster, Recipient pointing to User(Id)

I need to answer the following queries:

5. List Users who have posted comments to all female users

6. List User(s) who have received comments from the most number of users

When finding users, all I need to list is the Id of the user.

Neurofibromatosis Type 1 (NF1) is a human genetic disorder. As well as physical symptoms, affected children often suffer from impaired cognition and learning. A cognitive task that involves solving a puzzle is administered to a group of children. For each child the time taken (in seconds) to solve the task is recorded.

It is not known whether there is any suitable parametric model for the times so we will investigate non-parametric methods.

1. Calculate appropriate summary statistics and thus give the parameters for a normal distribution that may be applicable to these data.

2. Using the observed data, calculate the empirical distribution function. Plot the empirical distribution function and the CDF of the normal distribution described in (a) on a single graph.

3. Do you think the normal distribution is an appropriate model for the data? Justify your answer.

It is known that the mean time to solve the puzzle in healthy control children is 60 seconds.

The data for the observed times ?? taken by 57 children with NF1 are:

Assume that the population of a town obeys Malthusian growth. Assume that the size of the population was 2000 in year 1900, and 50 000 in year 1950.

(a) Find the value of the growth constant k.
(b) How long does it take for the population to grow by 20%?
(c) How big was the population in year 2000?
(d) What was the rate of change of the population in year 2000?
(e) Calculate the size of the population in year 2001, and from that the actual change in population during the one year, from 2000 to 2001.
(f) Explain why the two values calculated in (d) and (e) above do not necessarily have to be the same.

1. Describe the types of problem that can possibly occur in a multi-user environment when concurrent access to the database is allowed.
