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

Ounces Bottle Number

Ounces Bottle Number

Ounces

1 14.5 11 15 21 14.1

2 14.6 12 15.1 22 14.2

3 14.7 13 15 23 14

4 14.8 14 14.4 24 14.9

9 14.8 19 15.8 29 14.8

10 15.2 20 14.5 30 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

reason(s) behind the claim, and recommend one (1) strategy geared toward mitigating

this issue in the future.

 Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides. No citations and references are required, but if you use them, they must follow APA format. Check with your professor for any additional instructions.

MAT 300 Student Version 1144 (1261 3-24-2014)

Weekly Course Schedule

The purpose of the course schedule is to give you, at a glance, the required preparation, activities, and

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.http://www.strayerbookstore.com/
