- The book The Wall Street Journal. Guide to Information Graphics by Dona M. Wong gives strategies for using graphs and charts to display information effectively. One popular graph discussed is the donut pie chart. The donut pie chart is simply a pie chart with the center removed. A recent Harris Poll asked adults about their opinions regarding whether books should be banned from libraries because of social, language, violent, sexual, or religious content. The responses by education level to the question "Do you think that there are any books which should be banned completely?" are shown in the following donut pie charts.

A Computer Can Now Translate Languages as Well as a Human by Vanessa Bates Ramirez (excerpt) In other words, it’s finally happened: computers are smarter than people. In a contest that tested the new software against human translators, it came close to matching the fluency of humans for some languages. People fluent in two languages scored the new system between 64 and 87 percent better than the previous one. Google is already using the new system for Chinese to English translation and plans to completely replace its existing translation technique with the GMNT.A decision problem is described by the following decision tree (which has already been solved).

- Where is the decision tree and how do I fold it back?Mrs Moore is a agriculturalist and would like to drill for water on her farm. She needs water for irrigation and estimates the benefits of having a successful borehole as $2.0m. However, there is only a 10% chance that she will strike water if she drills and the cost of drilling is $100 000. The alternative is not to drill at all, in which case the benefit will be zero. Draw a decision tree to represent the problem. Should Mrs Moore go ahead and drill? There is another agriculturalist in a nearby state who claims to have supernatural powers to indicate underground water sources. However, he charges a fee and also travel cost. What is the most Mrs Moore should pay for the services? Before Mrs Moore drills, she could also consult a geologist who can assess the promise of the piece of land. He can tell her whether the prospects are “good” or “poor.” But he is not a perfect predictor. If there is water, the conditional probability is 0,95 that he will say that prospects are good. If…Identifying Spam Text Messages Bayes' rule can be used to identify and filter spam emails and text messages. This question refers to a large collection of real SMS text messages from participating cellphone users. 1In this collection, 747 of the 5574 total messages (13.40 % ) are identified as spam. The word "text" (or "txt") is contained in 7.01 % of all messages, and in 38.55 % of all spam messages. What is the probability that a message is spam, given that it contains the word "text" (or "txt")? Round your answer to three decimal places.
