1. The general least-squares problem is to find an $\vec{x}$ that makes $A\vec{x}$ as close as possible to $\vec{b}$. 2. A least-squares solution of $A\vec{x} = \vec{b}$ is a vector $\hat{x}$ that satisfies $A\hat{x} = \hat{b}$, where $\hat{b}$ is the orthogonal projection of $\vec{b}$ onto $Col(A)$. 3. A least-squares solution of $A\vec{x} = \vec{b}$ is a vector $\hat{x}$ such that $||\vec{b} - A\hat{x}|| \le ||\vec{b} - A\vec{x}||$ for all $\vec{x}$ in $\mathbb{R}^n$. 4. If the columns of A are linearly independent then $A\vec{x} = \vec{b}$ has exactly one least-squares solution. 5. If $\hat{x}$ is a least-squares solution of $A\vec{x} = \vec{b}$, then $\hat{x} = (A^TA)^{-1}A^T\vec{b}$. 6. The normal equations always provide a reliable method for computing least-squares solutions.

Quality in the News Guidelines Below are some guidelines to help you complete the Quality in the News assignment: 1. Assignment length: one page, typed. 2. Spelling errors and grammar errors always detract from the reader's final opinion of the work. Be mindful of these errors and proof read your work. 3. Complete the top of the template with your name and the date the assignment is due (not the date you write it). 4. Citations and references shall be in APA citation formatting. 5. Select a current news article from a general periodical (examples: New York Times, Wall Street Journal, Times Union, Time, Newsweek, US News and World Report, etc.). Professional publications and trade journals such as Harvard Business Review, Quality Progress, Quality Digest, Quality Management Journal, etc. should not be used. (If you have a question about a source, email me with your question). 6. Summarize the problem from the article and identify what you think the quality issue may be (It must start with - \"The quality problem is...\"). 7. Only identify one problem per assignment. 8. Think about the quality tools you can use to solve the problem and identify which three tools you would use and why you picked those particular tools. 9. You may not use the same tools from assignment to assignment; you must use three different/new tools for each assignment. 10. Identify at least the first three problem identification steps you would take to determine the root cause (list at least the first three actions). Do not restate any of your tools as problem solving steps. Your steps should not talk about solutions. (See slide 31 from lecture 4.) 11. You may not use the same steps from assignment to assignment; you must use three different/new steps for each assignment. Remember the point of this exercise is to read, think and question the issues; how these issues relate to quality and how you might start to solve this problem. This is not a writing exercise it is a thinking exercise. I am interested in a succinct, one page summary. Submit your paper in Moodle (Quality in the News section), attach a link to your article.
