Gallup recently conducted a survey about the proportion of Americans who use e-cigarettes (vape). The survey data was collected via random-digit-dial telephone interviews conducted July 1-12, 2019 with a random sample of 1525 adults living in all 50 U.S. states with a minimum quota of 70% cellphone respondents and 30% landline respondents, with additional minimum quotas by time zone within region. The following table summarizes their results for men and women: Men Women Total Vape 92 31 123 Do Not Vape 924 478 1402 Total 1016 509 1525 Problem 2. Does the data suggest that a greater proportion of men vape compared to women? Conduct a hypothesis test to at the 5% significance level by completing the following steps: State the null and alternative hypotheses. Be sure to include proper statistical notation. Check the conditions for inference. Compute the test statistic. For full credit, be sure to show your work. Determine the p-value or the critical value (depending on the method you prefer). Either way, be sure to show your work by drawing a sketch. Using either the p-value or critical value method, make a decision about the null hypothesis. Be sure to show how your decision was made. Based on the results of the hypothesis test, does it appear that “use of e-cigarettes” and “gender” are independent variables? In other words, is it equally likely for a man to vape as it is for a woman to vape? Explain. Would the results of the hypothesis test change at the 1% significance level? Explain.

1- An electron moving in a metal nanowire is a reasonable approximation of a particle in a one-dimensional infinite well. Suppose the electron is in a wire 10nm long. (a) Compute the ground-state energy for the electron. (b) The electron moves freely inside in metal nanowire. Find the electron’s velocity in ground state. c) If the electron’s energy is equal to 10 eV, what is the electron’s quantum number n?

2- Briefly explain the differences between quantum and classical thermodynamical approximation of electron energy.

3- Think about the electron where it is in first energy state in metal with length of L. (a) What would be the probability of finding it somewhere in the region 0< x< 3L/2? Find energy level corresponding energy state of the electron.

4- Find the second state electron energy (E2) by substituting the radial wave function R that corresponds to n=2 l=0 and mı=0

For this paper, I want you to put yourself in the position of the Vice President of a particular group (e.g., the VP of HIT Operations, the Department Head of a particular medical unit, the VP of IT). What is your leadership style of the future? How will you grow as a leader? Use your Leadership Journals to help with this. A key point to understand is that this paper complements the HIT Project Proposal. This paper will detail your approach to HIT leadership with a specific action plan to implement that HIT leadership approach. It is critical that you focus on HIT as you write the paper because, though some leadership and management principles are universal, the industry one works in comes with unique considerations.

Please do not underestimate the value of this assignment. Becoming a good leader means understanding yourself and being intentional about your growth. You may very well find yourself referencing this work for years to come as you grow and mature as an HIT leader.

Question text

In drosophila (fruit flies):

  • The yellow gene is on the X-chromosome, the gene product plays a role in body colour. Wild type flies are a light brown/tan in colour, homozygote yellow mutants have a more yellow shaded body colour. We'll use y+ to represent the wild type allele, and y to represent the mutant allele. y+ is dominant to y.
  • The vestigial gene is on chromosome 2. Homozygote vestigial mutants have very short wings, and cannot fly. We'll use vg+ to represent the wild type allele, and vg to represent the mutant allele. vg+ is dominant to vg.
  • The scarlet gene is on chromosome 3. Homozygote scarlet mutants have bright red eyes, while wild type flies have darker brownish-red eyes. We'll use st+ to represent the wild type allele, and st to represent the mutant allele. st+ is dominant to st.
  • Males are usually XY, and females are usually XX

You cross a female fly who is wild-type in phenotype and heterozygous for all three genes, with a male who has a yellow body, very short wings and bright red eyes. What is the probability their offspring will have very short wings and normal eyes, if body colour doesn't matter (i.e, they can be either yellow or wild-type in colour)? For full marks you must show your work.

You have been working at a local CPA firm for the last 2 years. At the beginning of the year, you passed the last section of the CPA Exam. Last week, your CPA License came in the mail. Consequently, you have now decided to go into business for yourself. You have some savings and have a line on a bank loan for start-up costs. Additionally, you do not have a noncompete clause in your employment agreement with your current CPA firm, and you have your own customers.

In your initial post, discuss the following:

  • Explain the authority that you have to practice and what duties you must complete practicing before the IRS.
  • Explain what restrictions, if any, you face in tax practice.
  • Explain on what ethical grounds you will base your practice and where you would draw the line to please your clients.

Define what a theoretical orientation is. Report the three theories that you matched most closely to and explain whether you think the assessment was accurate and why. State the theory that was indicated as the worst match for your view of human nature, explain what makes this theory so different from your point of view.

Mutations

1. Explain how a mutation in one of the hemoglobin subunit genes leads to symptoms of low blood oxygen, fatigue, and clogged capillaries. In your explanation, include the effect of the mutation on the primary, tertiary, and quaternary levels of protein synthesis and connect the protein’s attributes to the sickle-shaped red blood cells. In your explanation, compare the mutant subunit to the normal subunit.

Water is cooled to 32K, and it appears to be on the solid phase on the phase changing diagram as the temperature is low.


Water is cooled to 32K, and it appears to be on the solid phase on the phase changing diagram as the temperature is low. We compress the ice to a temperature of 340-350K (around 30ATM on the pressure dial).

a. Where is the red dot now located in the phase changing diagram? Would it be on the line between liquid and gas phases?

b. What does that position on them phase change diagram say about pressure and temperature?

c. What happens to the pressure when heat is added?

d. How can you make the red ball move into the gas phase on the phase change diagram (using water in a simulation where you you can increase/decrease temperature and pressure)
