A. The mean is 44 B. The standard deviation is 21.563
In order to figure out the means and standard deviations for each of these you need to first find the means by adding all the numbers up for each then divide them by the number of numbers listed. Next you need to figure out the median by sorting the numbers in ascending order, the median is the middle number. Next locate the sum of squared deviation which is important to locate because without it you will not locate the standard deviation number. In order to locate the sum of squared deviation by subtracting the listed number minus the means and then squaring the result. In addition you will need to add each end result and divide by the number of numbers. Next you will need to find the...

...Canada \$34.95 is a highly improbable event with three principal characteristics: It is unpre­ dictable; it carries a massive impact; and, after the fact, we concoct an explanation that makes it appear less random, and more predictable, than it was. The astonishing success of Google was a black swan; so was 9 / 1 1 . For Nassim Nicholas Taleb, black swans underlie almost everything about our world, from the rise of religions to events in our own personal lives. A BLACK SWAN Why do we not acknowledge the phenomenon of black swans until after they occur? Part of the answer, according to Taleb, is that humans are hardwired to learn specifics when they should be focused on generalities. We concentrate on things we already know and time and time again fail to take into consideration what we don't know. We are, therefore, unable to truly estimate oppor­ tunities, too vulnerable to the impulse to simplify, narrate, and categorize, and not open enough to rewarding those who can imagine the "impossible." For years, Taleb has studied how we fool our­ selves into thinking we know more than we actually do. We restrict our thinking to the irrelevant and inconsequential, while large events continue to surprise us and shape our world. Now, in this reve­ latory book, Taleb explains everything we know about what we don't know. He offers surprisingly simple tricks for dealing with black swans and ben­ efiting from them. Elegant, startling, and universal......
