In the late summer of 2008, a brief war broke out between the two countries—Russia and Georgia. Suppose you are a researcher interested in nationalistic attitudes in these two countries. You decided to use data from the World Values Survey, which is available at the following URL: http://www.worldvaluessurvey.org/. The data of interest are presented below on Russian respondents.

Age

Proud of Nationality?

15–29

30–49

50+

Very proud

738

132

279

Quite proud

940

227

388

Not very proud

523

133

238

Not proud at all

194

47

83

Return to the original data. Exactly 940 persons between the ages of 15 and 29 indicated that they were “quite proud” of their nationality. Suppose for the moment that only 840 persons between the ages of 15 and 29 were “quite proud” of their nationality. Keeping the other cells as they were originally, recalculate the value of the chi-square statistic and determine whether it is statistically significant. Explain why adjusting only one cell in Question #10 resulted in a different conclusion.

On a late May afternoon in 1984, a fire broke out in the “Haunted Castle” attraction at the Great Adventure Park in Jackson Township, New Jersey (Figure 4-1). Eight teenagers became trapped in the haunted house and subsequently died in the blaze. The maze-like “building” was actually a set of 17 interconnected truck trailers; guests walked from one trailer into the next. The dark walk-through haunted house included a variety of fright-provoking scenes, live actors, and a “strobe room.” Plastic...

Between 2006 and 2008, Sony and Toshiba were in a format war in the market for high-definition optical discs. Sony had developed Blu-ray discs whereas Toshiba had developed the HD-DVD format. Both producers were manufacturing players for their own format. However, unless Sony and Toshiba agreed on producing only one particular format, consumers were holding off their purchases.

2008 Summer Olympics in Beijing, China, in a world record of 9.58 seconds. That works out to be about 23.4 miles per hour over the course of the race. For a brief period during that sprint, Bolt reached an astounding 40 feet per second (27.51 mph). As a physical activity, running is very different from walking. In running, a person's legs flex and the muscles stretch and then contract during acceleration. As the runner's muscles release and absorb energy, the...

Consider a weapons producer that is selling guns to two countries that are at war with one another. Guns can be produced at a constant marginal cost of $10 per gun. The demand for guns in each of the countries is given by: p = 50 - 0.5Q (Country A) p = 20 - 0.25Q (Country B) a. If the weapons producer can charge different prices to each country, what price and quantity will it sell to each? b. If...
