Oil Quality Bank
The Trans-Alaska Pipeline System carries crude oil from Prudhoe Bay on Alaska’s North Slope 800 miles to the port of Valdez, on the southern coast of Alaska. The pipeline carries a mixture of different qualities of oil. Quality of oil is measured in API gravity degrees – the higher the degrees APT, the higher the quality. Because the pipeline mixed oils of different degrees, shippers in Valdez receive oil of different quality than they purchased. To compensate shippers, a “Quality Bank” was established. The owners of the pipeline proposed compensating shippers 15 cents per barrel for every degree below the level to which the shippers agreed. However, a refinery near Fairbanks, which receives 26-degree oil and mixes it with 20-degree oil, objected to the proposal. It suggested a 3.09 – to 5.35-cent differential. Because oil carriers are required to establish “just and reasonable” rates, a hearing before an administrative law judge was held. At the hearing, an expert hired by the shippers produced the accompanying table to show the relationship between quality and price per barrel of Mideast oil.

Magnitude 7 Earthquakes
I was watching television news on CNN or Fox ( I forget which network) after the recent large 2010 Chile earthquake. They had a “scientific expert” who said that were an increasing number of large earthquakes. Being a statistician this did not sound correct. So I found the following data from the USGS at: http://earthquake.usgs.gov/earthquakes/eqarchives/year/eqstats.php.

Diamond Ring Prices.xls
The source of the data is a full page advertisement placed in the Straits Times newspaper issue of February 29, 1992, by a Singapore-based retailer of diamond jewelry. The advertisement contained pictures of diamond rings and listed their prices, diamond content, and gold purity. Only 20K ladies' rings, each mounted with a single diamond stone, were considered for this study. 20K rings are made with gold of 20 carat purity. (Pure gold is rated as 24K.) There were 48 such rings of varying designs. The weights of the diamond stones ranged from 0.12 to 0.35 carats (a one carat diamond stone weighs 0.2 gram) and were priced between $223 and $1086. The jewelry store adopted a fixed-price policy. How Is Jewelry Priced? In Singapore, the pricing of gold jewelry is simple. The price equals the current market value of the gold content (i.e., weight times the going rate per gram of gold) plus a craftsmanship fee. However, the pricing of other jewelry like diamond rings is more complicated because they are not as standardized as gold jewelry. The price of diamond jewelry depends on the four C's: caratage, cut, colour, and clarity of the diamond stone. A good cut gives a diamond more sparkle. Colourless diamonds are the most prized. A flawless diamond has maximum clarity because the passage of light is unimpeded through the stone. Cut, colour, and clarity are subjective factors and are very hard for the layman to gauge.

Heart Stent Data.xlsx
A coronary stent is a tube placed in the coronary arteries that supply the heart, to keep the arteries open in the treatment of coronary heart disease. It is used in a procedure called percutaneous coronary intervention (PCI). Stents reduce chest pain, but they have not been shown to improve survival, except in acute myocardial infarction.[1] Similar stents and procedures are used in non-coronary vessels e.g. in the legs in peripheral artery disease.
