An object of mass m1 approaches with velocity v1 another object of mass m2, which is at rest, next to a spring having force constant k. The spring is fixed to a wall and m2 can compress the spring. This is one-dim horizontal collision without friction. We consider two collision scenarios, one which is perfectly inelastic, and the other which is elastic. (a) In the first collision case the object m1 strikes m2 and sticks. Moving together, they compress the...

6. Two-tailed hypothesis testing - Step by step S-adenosyl methionine (SAM-e) is a naturally occurring compound in human cells that is thought to have an effect on depression symptoms. Suppose that a researcher is interested in testing SAM-e on patients who are struggling with Alzheimer’s. She obtains a sample of n = 20 patients and asks each person to take the suggested dosage each day for 4 weeks. At the end of the 4-week period, each individual takes the Beck...

4. You sample 1,000 college graduates, and regress their annual salary (in dollars) from 5 years after graduation on their college GPA (on a scale from 1.0 to 4.0). You estimate the following regression model, salaryi =20,000+12,000GPAi. e. Suppose there is a dummy variable Private that is equal to 1 if the student graduated from a private college, and 0 if they graduated from a public college. If private is positively correlated with both salary and GPA, is GPA endogenous...

Scientists at Wake Forest Baptist Medical Center have found new evidence that mindfulness meditation reduces pain more effectively than placebo. The research, published in the Nov.11, 2015 issue of the Journal of Neuroscience, showed that study participants who practiced mindfulness meditation reported greater pain relief than placebo. Significantly, brain scans showed that mindfulness meditation produced very different patterns of activity than those produced by placebo to reduce pain. The study used a two-pronged approach -- pain ratings and brain imaging...
