The equilibrium electron concentration is given by the product of density of states and probability function, n(E) = g_c(E)F(E)n(E)=gc​(E)F(E) whereg_c(E)gc​(E) and F(E)F(E) are the conduction band density of states and Fermi-Dirac probability function, respectively

Using the full expression of Fermi-Dirac function, calculate the energy relative to the conduction band edge, E-E_cE−Ec​, at which the electron concentration becomes maximum. This semiconductor has a bandgap of 1.124 eV and the temperature is 300 K. Further assume that the Fermi level, E_FEF​ is located precisely at the middle of the bandgap, i.e. E_C - E_F = \frac{E_g}2EC​−EF​=2Eg​

UV is a 55-year-old man who is seen during follow-up after being diagnosed with Type 2 diabetes. At the last visit, he has prescribed metformin 500 mg twice daily. UV states that he never filled his prescription, but instead took his neighbors advice and started taking cinnamon. He said that he googled the spice and found that it lowers blood sugar. Upon further questioning, he states that he grabs a spoon from the drawer and consumes baking cinnamon found in his kitchen cabinet.

Individuals experience various mood states or emotions at varying times every day, both subtle changes and obvious changes, that can result in attitude alternations with both negative and positive effects and impair or facilitate performance. The connections in the brain between emotion and memory have been particularly interesting to researchers given that neural networks that are activated by mood states are linked with neural networks that process basic perceptual functions such as word processing. Dr. Siebert has conducted a number of research experiments inducing various mood states through the use of music and then studying the effects of mood on lexical processing. In this study, higher scores on the Mood State measure reflect higher levels of lexical processing. The average Mood State score is μ = 3. (Dr. Pennie S. Siebert)

Social networking is becoming more and more popular among school-going teenagers. Camden Research Group used a survey of students in several states to determine the percentage of students who use social networking sites. Assume that the results for surveys in Georgia, Maryland, Washington, and Wyoming are as follows.

Answer the following 6 questions.

1. We wish to conduct a hypothesis test to determine whether the proportion of students using social networking sites are equal for all four states. What is the value of your test statistic?

2. True or False: At least one state's population proportion is different from the others. (5% significance)

3. What is the sample proportion for Georgia?

4. Which state has the largest sample proportion?

5. Using the multiple comparison procedures, answer the following:

True or False: There is a significant difference between Georgia and Maryland. (5% significance)

6. Using the multiple comparison procedures, answer the following:

True or False: There is a significant difference between Wyoming and Maryland. (5% significance)

Minister of labour, Thulas Nxesi, has gazetted South Africa’s new minimum wage which will take effect from 1 March 2020. The gazette states that the new national minimum wage is R20.76 – an increase of 3.8%”.

Provide a discussion on the welfare effect of the above, that illustrates the case for when the above results in unemployment in the market for domestic workers as well as a case for when the above has no effect on the market for domestic workers. Use a diagram to support your discussion.

Mr. Hulchanski callls the physician's office and speaks with Becky Smith, the medical assistant. Mr. Hulchanski has had recent surgery and was instructed to call the office in one week to report how he is doing. Mr. Hulchanski reports that he is feeling fine and that the surgical incision looks like it is healing well. He says the only thing that he has noticed is that when he awakens in the morning, his pajamas and linens are soaked. Becky asks if he has been running a fever, and he states that he has routinely taken his temperature several times during the day and it has been normal. In fact, he states that he is sure he is not having a fever because he actually feels chilled at times. Becky states that she is glad to hear that he is doing so well and to call back if any problems develop.

1. Becky documents "patient reports he is doing well and will call back if any problems develop." Is this the correct note to make in the chart? Why or why not?

2. Did Mr. Hulchanski report any variances from the norm?

3. What could possibly be happening to Mr. Hulchanski?
