In the past, some students have tried to use ridiculously small samples so you should give me an idea of your sample size. I would just like a brief statement of what you are planning to do your project on (e.g., a paragraph or two). You can later change your topic (but you should talk to me). Include an explanation of your data source. The data source should to be one that you have actually found and verified and not...

GardenTraker Suppose that you and some other students have done lawn care, or been groundskeepers, and you have decided to go out on your own and open a business that offers landscaping services. Your goal is to develop a list of clients for whom you provide regular and recurring services, such as mowing and weeding, plus specialty services, such as pruning, garden preparation, sprinkler installation and repair, and the like. You need an information system for tracking customers, services you...

1. Synthetic organic chemists have established clever ways for probing the mechanisms of chemical reactions. In general, a preference for anti- periplanar elimination is observed; however, under some conditions the syn-periplanar elimination product can be observed. How do chemists tell the difference between anti-and syn-periplanar eliminations? Let's find out! The reaction of the substrate below under E2 conditions (NaOEt in ethanol) will give different products by syn- and anti- elimination mechanisms. By analyzing the distribution of the products, organic chemists...

Some female psychology students were investigating whether intelligence depends on brain size. They each took a standard test that measured verbal IQ and also underwent an MRI scan to measure their brain size. The resulting data are in the file IQBrain.csv. The variables are IQ Result of the verbal IQ test. IQ is measured on an artificial index scale, usually meant to have an average value of 100. BrainV Brain volume measured in thousands of ‘pixels’. The size of a...

2. List some familiar adaptations animals have to reduce the effects of temperature extremes on their many vital, enzyme-catalyzed reactions. 3. In general, the rates of chemical reactions double for every 10 degrees (Celsius) increase in temperature. What changes at the molecular level account for slower reaction rates of enzyme- catalyzed reactions at high temperatures? (Hint: enzymes are protein molecules. What happens to protein molecules when they are heated?) Why are enzyme catalyzed reactions also slower at low temperatures? (Hint:...

Some statistics instructors have students use an online homework system and some do not. Final exam scores were recorded for a sample of statistic students who used an online homework system and were compared to the final exam scores from a sample of statistic students who did not use an online homework system. Is there evidence that the students who used an online homework system did better on the final? a) Test at the 3% level. b) Compute a 94%...
