According to http://www.gasandoil.com/goc/news/ntl50398.htm , accessed on Feb 2, 2005, “17-12-04 Jamaica has found signs of oil in 10 exploratory wells drilled into deep underground structures. Now it's come to Houston looking for oil companies willing to help the island nation, which depends heavily on tourism, bauxite and alumina, to become the world's next oil and natural gas producer. Hopeful Jamaican officials traveled to Houston promoting the nation's first formal license round, offering 22 offshore blocks and four on-shore blocks. "There are plenty of reserves yet to be found -- exploration in new frontiers is now warranted," said Raymond Wright of the Petroleum Corporation of Jamaica, reflecting on the world's supply dilemma. Oil explorers order seismic tests to determine whether oil is likely to be found in a certain drilling area. These seismic tests have a known reliability: When oil exists the tests indicate so 85% of the time and when oil does not exist the…
Once QBA 362 final exam is done, it will be time to reward Professor Hong with a well-deserved vacation. As a state employee, professor Hong hasn’t seen a raise since... well, ever.Thus, an important criterion, in fact the most important criterion is to find an exoticregion that can be visited inexpensively. There are three states of nature that could impact costs in these five areas of interest. Professor Hong has determined the average cost per day to visit each region under each of the possible states of nature. This table, which should not be construed as actual vacation advice, appears below. (Remember they are costs. Lower is better. For example, the most optimistic case is the one with lowest cost.)

Chapter 6, Section 4-HT, Exercise 218 - MathPad Mind-Set MattersIn 2007 a Harvard psychologist set out to test her theory that ‘‘Mind-Set Matters.”1 She recruited 75 female maids2 working in different hotels to participate in her study, and informed 41 maids (randomly chosen) that the work they do satisfies the Surgeon General’s recommendations for an active lifestyle (which is true), giving the maids examples on how their work qualifies as good exercise. The other 34 maids were told nothing. After four weeks, the exercise habits of the two groups had not changed, but the informed group had lost an average of 1.79 lbs (s=2.88) and the uninformed group had lost an average of 0.2 lbs (s=2.32). The data are stored in MindsetMatters. Based on this study, does ‘‘Mind-Set Matter”? In other words, for maids, does simply thinking they are exercising more actually cause them to lose more weight?Click here for the dataset associated with this question.1Crum, A. and Langer, E.,…

The data file includes the text of three books of the Bible (Joshua, Jonah and Philippians) using the ESV translation. While these are all great books, our only interest for this project is how often each letter is used. Identify those letters whose Cls do not overlap with any the CIs of any of the other letters. (For example the CI [0.042, 0.052] overlaps with [0.050, 0.060] because the upper bound of the first CI is greater than the lower bound of the second CI.) List the letters with the non-overlapping Cis and specify how many such letters there are.
In the past few weeks people have been arguing on the social media forum https://www.reddit.com/r/ontario/ about whether the COVID-19 situation in Ontario was improving or getting worse. Some users call those who focused on high spikes in new cases "doomers" (as in "ok doomer") such as the 460 new cases on Sunday May 24. Recently the numbers of new cases have gone down to 287 on Tuesday the 26th and 292 for Wednesday the 27th.
