The data and fields file will be provided by your lecturer at the commencement of the class. The data relates to nutrition of breakfast cereal. Suppose that you are an Analytics team for a sport and dieting company. You have been given data on the nutritional components (e.g. sugar, fat, protein…) of common breakfast cereals and a rating. You wish to determine which cereals are best for diabetics and those on special diets. PLEASE TYPE OR SEND ME STEPS BY STEP IN THE WORD DOCUMENT HOW YOU GET THAT ANSWER. Upload the data into Excel for an initial check. The file is a csv (txt) file. Check for missing data and errors.
a. State the number of data records you have in the sample
b. You may notice some negative values which can be modified using an approximate based on a similar product and state your changes.
c. Provide any assumptions, changes and issues presented in the data that may impact your analysis
d. Sort the ratings from largest to smallest to get an idea of general customer approval of the cereals and state the cereal with the highest and lowest approval rating
e. Save the file as an Excel file for uploading into Power BI or Tableau.

Learning Outcome(s):
Design a database starting from the conceptual design to the implementation of database schemas
Question Three Consider a database schema with the following tables:
CREATE TABLE Students (
StudentID INT PRIMARY KEY,
Name VARCHAR(50),
Age INT,
GPA FLOAT );
CREATE TABLE Courses (
CourseID INT PRIMARY KEY,
CourseName VARCHAR(50) );
CREATE TABLE Enrollments (
EnrollmentID INT PRIMARY KEY,
StudentID INT,
CourseID INT,
Grade FLOAT,
FOREIGN KEY (StudentID) REFERENCES Students(StudentID),
FOREIGN KEY (CourseID) REFERENCES Courses(CourseID));
Solve the following SQL problems by nesting queries.
Write an SQL query to find the names of students who are enrolled in the course ‘Mathematics’ and have a GPA greater than 3.5.
Assuming the same database schema, write an SQL query to find the average GPA of students who have enrolled in the course ‘Physics’.
Extend the previous query to find the average GPA of students who have enrolled in the course ‘Physics’ and whose age is less than 25. Learning Outcome(s):
What does “URL” stand for?
a) Universal Resource Locator
b) Uniform Resource Locator
c) Unified Resource Locator
d) Unilateral Resource Locator
Injuries in Military Training
Purpose of the project: From an existing data set you will select 1
dichotomous injury outcome and up to 12 risk factor variables. Using your
selected outcome and risk factors, you will perform the analysis, and then
write-up a Methods and Results section of a scientific manuscript.
A successful completed project will include:
A ONE sentence statement of the purpose of your study.
A concise Methods section of how you met your stated purpose.
A concise Results section on your findings. Included in this
section will be 4 tables:
1. Descriptive frequencies of all variables
2. Univariate associations of all variables with your outcome.
3. A general logistic regression model.
4. A final logistic regression model.
The total word count for the entire project (excluding tables) will be
no more 1200 words. Sections 2 and 3 should be written as if they are
part of a final manuscript being submitted to a journal. 1200 words is
not very much, and the toughest part of these sections will be to stay
within the word count limit.
Background: U.S. Marine Corps recruit training was a 12 week training
program required for all personnel enlisting in the Marine Corps. The
Recruit Training Regiment (RTR), in San Diego, CA, takes men who are
arriving directly from their homes, and produces Marines at the end of
training. Recruit training is a very physically arduous training
program with the goal of producing the most physically fit Marine
possible at the end of 12 weeks. During training, a proportion of
recruits suffer a musculoskeletal injury and seek medical attention.
As part of an effort to develop a fitness curriculum which produces the
greatest fitness improvement while keeping injuries to a minimum, a
study was performed to identify risk factors of injury during training.
A literature search was performed to identify established and potential
risk factors for injury during an arduous physical fitness program.
From this search, a list of risk factors was developed for
investigation. Upon arrival at RTR, a 5% random sample of these
apparently injury-free incoming recruits were asked to volunteer, and
those providing consent were assessed for these risk factors using a
questionnaire. 94% of the sample agreed to participate. The
enrollment process continued for 6 months. After filling out the
questionnaire, recruits were observed over their 12 weeks of training.
Throughout the observation period, any injury reported to the medical
clinic by an enrolled recruit was recorded
The questionnaire used tocollect risk factordata is provided.
There are a number of outcomes for you to choose from. They
are labeled:
STRFX – Stress Fracture
Anklefoot – Ankle or foot injury
Knee – knee injury
Overuse – injury in any location from overuse
Acute – injury in any location from an accident
ITBS – ilio-tibial band tendonitis
Injured – any injury for any reason
HPT – injury to hip, pelvis, or thigh
Pick ONE outcome of interest from above and select your
exposure of interest and up to 11 covariates from the
questionnaire

Project I
Database System for a car rental company
Consider the company requirements as follows:
A car rental company needs a comprehensive database system to streamline its operations. The system should enable customers to rent cars from multiple locations (Riyadh, Jeddah, Makkah, Dammam, Al-Khobar, Qasim, Tabuk, AL-Baha, Al-Jawf, Ha’il, Aseer, Jazan, Najran). Customers will be required to register by providing their full name, email, phone number, and date of birth. The company owns a fleet of cars, which contains important details such as the manufacturer, model, manufacturing year, license plate, and daily rental rate. Every rental transaction will involve the customer, the rented car, and the rental period (start and end dates). As the company operates in multiple cities and states, multiple rental locations are available, each with its name, street address, city, state, and postal code.
Customers can rent multiple cars, and each car can be rented by multiple customers. A specific rental location will be associated with each car. Moreover, each rental transaction will be linked to a specific rental location. To maintain data integrity, constraints such as unique customer and car IDs will be enforced. Rental transactions must be associated with both a customer and a car.
On the other hand, each car should be linked to a rental location. Reports on rental transactions will be generated, including customer information, location, and period. User roles will be implemented for customers and system administrators. Customers will be able to view available cars, rent cars, and access their rental history. Meanwhile, administrators will be able to manage car inventory, rental locations, and customer accounts.
The system will ensure that cars are available for rent at specific locations and track car availability to prevent overbooking. Rental costs will be calculated based on the rental rate per day. User authentication and authorization will be implemented to protect customer data and system operations.
