Exam Tip: The rules for means and variances when you combine random variables may seem a bit obscure, but there have been questions on more than one occasion that depend on your knowledge of how this is done. The rules for means and variances generalize. That is, no matter how many random variables you have: m X1 X2 ... Xn = m X1 m X2 ... + mXn and, if X1, X2,..., Xn 2 2 2 2 are all independent, X1 X 2 Xn = X1 + X 2 + + X n . example: A prestigious private school offers an admission test on the first Saturday of November and the first Saturday of December each year. In 2002, the mean score for hopeful students taking the test in November (X ) was 156 with a standard deviation of 12. For those taking the test in December (Y ), the mean score was 165 with a standard deviation of 11. What are the mean and standard deviation of the total score X + Y of all students who took the test in 2002 solution: We have no reason to think that scores of students who take the test in December are influenced by the scores of those students who took the test in November. Hence, it is reasonable to assume that X and Y are independent. Accordingly, X +Y = X + Y = 156 + 165 = 321,

In this experiment the heat change associated with a process is calculated. Various substances are added to a calorimeter (usually a polystyrene cup), and the initial and the final temperatures are measured. (See the Stoichiometry chapter.)

One of the inherent flaws in using the standard eBay sell form is that the layout places the text first and images at the bottom. Buyers find it irritating to have to scroll down to the bottom to see pictures of the item. And when they have to do so, the seller also runs the risk of the dreaded click factor. Using HTML to embed photos into the item description partially solves this problem but tends to increase the necessity for the user to scroll down even more. The best solution to this problem is to utilize tables in your item listing. An HTML table allows you to lay out your item listing with images and text side by side. eBay s Listing Designer and other third-party listing design tools all offer the table option. Table usage is Web-standard practice. If you hire someone to custom design a template, you should be sure that she includes HTML tables in your listing templates. Tables increase the usability of your listing. With this effective layout technique, potential customers can see the images and read the description at the same time, with minimal scrolling and clicking. It s the combination of the visual cue of the image with the information of text that keeps the viewer engaged with your listing. This prevents boredom and click-aways and inspires purchases. Figure 3-4 demonstrates an HTML table format layout in an eBay listing.

needs to focus on core-level needs rather than edge-level needs. As you move to the edge of the network, you start to find hundreds, thousands, tens of thousands, and hundreds of thousands of nodes. A migration at the edge level is invariably going to take several years, if not even a decade or so. Also, there may be international opportunities (to interconnect between continents) and a handful of greenfield applications. These are discussed in Section 8.5. Therefore, the migration to VoMPLS/VoP will likely follow these rules:
