Question 4 – 15 points 4. Some radioactive nuclei, e.g. Phosphorus-32, emit electrons (“beta radioactivity”). Here we consider if Gamow’s model of radioactivity can be applied to understand beta emission. 4a) As in the case of alpha emission, consider the electron to be trapped inside the original nucleus in a square well. Outside the square well, the electron will feel the Coulomb force due to the final nucleus. Write an expression for the energy of the electron as a function of the distance from the nucleus. 4b) Sketch the potential of part a).   4c) Discuss if Gamow’s model can be applied to beta decay.

A characteristic that distinguishes true experiments from weaker experimental designs is that true experiments include:

A hospital administrator is examining gender differences in annual salary among health care executives. He hypothesizes that the average salary for men is higher than that of women. He collects data on a random sample of 14 male and 15 female CEOs. He runs the appropriate statistical analysis and concludes that there is no difference in salary based on gender. Which of the following is most likely TRUE about this study?

The article Wechsler, H. (1995). A gender-specific measure of binge drinking among college students. American Journal of Public Health, 85, 982-985 should be cited in the text of a literature review as:

While there are no specific examples of science as a way of knowing in the Bible, research is important to God.

A Type 1 error can occur if the sample size is too big.

When Sue (2006) talked about cultural competency in practice, he indicated three processes in counseling: scientific mindedness (i.e., forming and testing hypotheses), _____ (i.e., flexibility in generalizing and individualizing), and culture-specific resources (i.e., having knowledge and skills to work with other cultures).
