  1. Over the past year, the vice president for human resources at a large medical center has run a series of three-month workshops aimed at increasing worker motivation and performance. To check the effectiveness of the workshops, she selected a random sample of 35 employees from the personnel files. She collected the employee performance ratings recorded before and after workshop attendance and stored the paired ratings in the Excel data file for this assignment under the tab Perform.   

Conduct the appropriate hypothesis test and then state your findings and conclusions regarding the value of these workshops. (Significance level of 5%)

  1. State your null and alternative hypothesis.
  2. What is the conclusion of your test? Justify your answer, including an interpretation of the confidence interval and the p-value.
  3. Assuming the cost of the training is $1000 per employee, what would be your decision regarding these workshops under the assumption that an increase in performance of at least 10% would justify the cost?

a) Explain that in a one-dimensional system, although a system with an even number of electrons per primitive unit cell is insulator, this does not apply to three-dimensional systems.
b) How the electron state density behaves around the maximum of the valance band and the minimum of the conductivity band of a semiconductor or insulator.
c) Explain why a fully charged band does not contribute to electrical conductivity when an electric field is applied.
d) How does the Bloch wave vector change over time when an external electric field is applied in the effective mass approach?
e) Show that the state density for free electron gas is not dependent on energy in two dimensions. How to relate to energy in one and three dimensions.

An insurance agent sells dental insurance, medical insurance, and life insurance. He checks sales since the beginning of the year and finds that he has sold 50 dental, 48 medical, and 28 life insurance policies. Some customers purchased more than one type: 22 bought both dental and medical, 18 bought both medical and life, 12 bought both dental and life, and 8 bought all three types. How many of these customers bought exactly one of the three types of insurance from the agent this year?
