MAT 300 – Assignments and Rubrics
ALEKS Pie Completion Worth 400 points
The primary goal of this class is for you to complete the entire pie by the end of the term. Points for pie completion will be added to your score at the end of the term.

ALEKS
Emphasis on Lab Work. On-ground sections of the course will be taught in a computer lab, with three (3) hours of lab time using ALEKS for every one (1) hour of traditional instruction. Thus, students in an onground section of the course will log about three (3) of the required five (5) weekly hours in ALEKS during class. To get full credit for the ALEKS participation points, on-ground students will have to put in two (2) additional hours using ALEKS outside of class. Online students will also utilize ALEKS in the same or similar manner. All students will start the term by taking a comprehensive ALEKS assessment to identify where they need to focus their efforts. As you master each assigned topic, your progress will be plotted on a pie chart. Your goal will be to fill in the entire pie. Forty (40) percent of your final grade will be based on how much of the pie you fill in. Weekly Lab Requirement. Students are expected to spend at least five (5) hours per week working with ALEKS. The instructor will be able to see how much time you’ve spent in ALEKS and what topics you’ve worked on. Weekly ALEKS time will count toward 10% of your final grade. If you work in ALEKS for five (5) or more hours, you will earn ten (10) points. If you spend less time working in ALEKS, you’ll receive partial credit in direct proportion to the time you spend, at 2.0 points per hour. Please note that five (5) hours is the minimum requirement each week. Generally, the more time you can spend working on the pie, the more you will progress. We recommend that students spend at least six (6) hours each week in ALEKS. If you fill in the ALEKS pie early, your instructor will provide instructions on how to access an expansion pie with advanced topics covered in the next math course, so that you can continue to learn new material while meeting the ALEKS lab requirement. Pacing and Weekly Objectives. While each student will work through a unique ALEKS pathway, this course is being taught in the context of an 11-week term. To assist students in pacing their efforts, weekly objectives have been established. These appear as white dots on your pie chart. Halfway through the term, all students will complete a Midterm Exam, based on the weekly objectives for the first four (4) weeks. Repeating Exams. Students may repeat the Midterm and the Final Exam one (1) time each. Please note that students who score poorly on the Midterm Exam should consult their instructor before taking the exam a second time. Typically, students who score poorly on the Midterm Exam have not completed at least sixty (60) topics in their ALEKS pie. Those in this situation are advised to complete at least sixty (60) topics in the ALEKS pie before retaking the Midterm Exam. Discussion Requirement. Students taking the course on-ground will receive points for class participation and attendance, based on the criteria set by the instructor. Students taking the course online must participate in the online discussion boards each week in Blackboard to earn points for discussion. Discussion makes up 10% of the overall final grade.

Assignment 1: Bottling Company Case Study Due Week 10 and worth 140 points Imagine you are a manager at a major bottling company. Customers have begun to complain that the bottles of the brand of soda produced in your company contain less than the advertised sixteen (16) ounces of product. Your boss wants to solve the problem at hand and has asked you to investigate. You have your employees pull thirty (30) bottles off the line at random from all the shifts at the bottling plant. You ask your employees to measure the amount of soda there is in each bottle. Note: Use the data set provided by your instructor to complete this assignment. Bottle Number 1 2 3 4 5 6 7 8 9 10 Ounces 14.5 14.6 14.7 14.8 14.9 15.3 14.9 15.5 14.8 15.2 Bottle Number 11 12 13 14 15 16 17 18 19 20 Ounces 15 15.1 15 14.4 15.8 14 16 16.1 15.8 14.5 Bottle Number 21 22 23 24 25 26 27 28 29 30 Ounces 14.1 14.2 14 14.9 14.7 14.5 14.6 14.8 14.8 14.6

Write a two to three (2-3) page report in which you: 1. Calculate the mean, median, and standard deviation for ounces in the bottles. 2. Construct a 95% Confidence Interval for the ounces in the bottles. 3. Conduct a hypothesis test to verify if the claim that a bottle contains less than sixteen (16) ounces is supported. Clearly state the logic of your test, the calculations, and the conclusion of your test. 4. Provide the following discussion based on the conclusion of your test: a. If you conclude that there are less than sixteen (16) ounces in a bottle of soda, speculate on three (3) possible causes. Next, suggest the strategies to avoid the deficit in the future. Or b. If you conclude that the claim of less soda per bottle is not supported or justified, provide a detailed explanation to your boss about the situation. Include your speculation on the reason(s) behind the claim, and recommend one (1) strategy geared toward mitigating this issue in the future. Your assignment must follow these formatting requirements:  Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides.

Weekly Course Schedule
The purpose of the course schedule is to give you, at a glance, the required preparation, activities, and evaluation components of your course. For more information about your course, whether on-ground or online, access your online course shell. The expectations for a 4.5 credit hour course are for students to spend 13.5 hours in weekly work. This time estimate includes preparation, activities, and evaluation regardless of the delivery mode.

Instructional Materials
In order to be fully prepared, obtain a copy of the required textbooks and other instructional materials prior to the first day of class. When available, Strayer University provides a link to the first three (3) chapters of your textbook(s) in eBook format. Check your online course shell for availability. Review the online course shell or check with your professor to determine whether Internet-based assignments and activities are used in this course. Strayer students are encouraged to purchase their course materials through our designated Strayer Bookstore. http://www.strayerbookstore.com If a lab is required for the course, the Strayer Bookstore is the only vendor that sells the correct registration code so that Strayer students may access labs successfully.

Discussions
To earn full credit in an online threaded discussion, students must have one original post and a minimum of one other post per discussion thread. Please note: Material in the online class will be made available three weeks at a time to allow students to work ahead, however, faculty will be focused on and responding only to the current calendar week. As it is always possible that students could lose their work due to unforeseen circumstances, it is a best practice to routinely save a working draft in a separate file before posting in the course discussion area. Professors hold discussions during class time for on-ground students. Check with your professor if any additional discussion participation is required in the online course shell outside of class hours.

Tests
Tests (quizzes, midterm and final exams, essay exams, lab tests, etc.) are available for student access and completion through the online course shell. Check the online course shell to determine how students are expected to take the tests. Do not change these questions or their point values in any way. This disrupts the automated grade book preset in the online course shell.   Online students are to complete the test by Monday 9:00 a.m. Details regarding due dates are posted in the Blackboard Calendar tool. On-ground students are to complete the tests after the material is covered and before the next class session.
