An article included data from a survey of 2779 hiring managers and human resource professionals. The article noted that many employers are using social networks to screen job applicants and that this practice is becoming more common. Of the 2779 people who participated in the survey, 1100 indicated that they use social networking sites (such as Facebook, MySpace, and LinkedIn) to research job applicants.

a) For the purposes of this exercise, assume that the sample is representative of hiring managers and human resource professionals. Construct a 95% confidence interval for the proportion of hiring managers and human resource professionals who use social networking sites to research job applicants. (Round your answers to three decimal places.) ( , )

1. Why are aminoglycosides more selectively toxic to bacteria than human cells? (Be sure to be complete and specific in your answer to make it clear why these drugs are more toxic to bacterial cells than to human cells.)

2. Penicillins and cephalosporins are beta-lactam antibiotics. Plasmids coding for beta-lactamase enzymes make the bacterium resistant to these antibiotics. What do beta-lactamases do?

3. The malarial organism possesses the remnants of a chloroplast, called an apicoplast. How does tetracycline inhibit growth of the malarial organism? Be sure to make it clear why it is more toxic to cells of the pathogen than human cells in your answer. "Because it has an apicoplast" is not a sufficient answer!

A little-known fact: According to Pets.WebMD website: For dogs under 21 pounds in weight, the conversion from a dog’s age to an equivalent human age is:
1st year: 15 years
2nd year: add 9 years
thereafter: add 4 years for each additional year of the dog’s age
So, for example, a dog aged 5 would have an equivalent age of (15+9+4+4+4), or 36 human years old.   

Write a lambda expression called convertToHuman, using a standard functional interface, that will take a given dog and return the equivalent human age . [Assume dog weighs less than 21 pounds]

Write between 5 and 7 pages on Smallpox Eradication – The Most Famous Success Story. (Somalia 1977, Latin American 1971, and Asia 1975.)

Address the following questions below, should be as a report.

1. Describe the demographics of the population presented in the case study.

2. Which sustainable development goals should be considered when addressing the health disparities identified in this scenario?

3. What do the indicators of DALYs and HALEs tell you about the burden of disease in the country?

4. Applying the health and human rights approach to global health:

1. Assess the health policies, programs, and practices in terms of their impact on the human rights of the country in this case study.

2. Address the health impact resulting from the violation of human rights when considering improving the health of this population.

3. Explain what needs to be done in this case scenario to prioritize the fulfillment of human rights.

5. Discuss at least three to five factors that were important contributors that led to the success of program implementation and are considered valuable lessons learned.

1. Bradford Company has two service departments, Human Resources and Janitorial, and two production departments, Cutting and Glazing. The following data have been estimated for next year’s operations:

Requirements:

(1)   Distribute the service department costs using the sequential distribution method. Distribute the Human Resources Department first. (24 points/3 points each)

(2) Prepare the journal entries to distribute the costs of the service departments to the production departments given the results of your calculations. (16 points/8 points each)

Question1: Define a class Human that contains: - The data fields "first name" and "last name" - A constructor that sets the first and last name to the instance variables. Create also a no-argument constructor - A getName() method which prints the first and last name Define the class Student which inherits Human and contains: - Private data field "mark" of type integer and a constructor which calls the superclass constructor Define the class Worker which inherits Human and contains: - Private date fields "wage" and "hours worked", and a constructor which calls the superclass constructor - A setWageInfo() method which sets the wage information to the instance variables - A calculateWage() method which calculates a worker’s salary based on wage and hours worked Write a program called HumanTest that instantiates two Human objects (one using the noargument constructor and another using the constructor with parameters). Call the method getName(). Create a Student object which calls the getName() method. Create a Worker object which calls the methods getName(), setWageInfo(), and claculateWage().

An article included data from a survey of 2658 hiring managers and human resource professionals. The article noted that many employers are using social networks to screen job applicants and that this practice is becoming more common. Of the 2658 people who participated in the survey, 1100 indicated that they use social networking sites (such as Facebook, MySpace, and LinkedIn) to research job applicants. For the purposes of this exercise, assume that the sample is representative of hiring managers and human resource professionals.

(a)

Assuming that this sample is random/representative of the population, what other assumptions need to be true before we can create a confidence interval?

Yes, because

n ≥ 30

No, because the population distribution is not normal.    Yes, because

np̂ ≥ 10

and

n(1−p̂)≥ 10

No, because either

np̂ < 10

or

n(1−p̂) < 10

No, because

n < 30

Yes, because the population distribution is normal.

(b)

Construct a 95% confidence interval for the proportion of hiring managers and human resource professionals who use social networking sites to research job applicants. (Round your answers to three decimal places.)

   ,  

(c)

Interpret a 95% confidence interval for p, the proportion of all hiring managers and human resource professionals who use social networking sites to research job applicants

We are  % confident that the proportion of all hiring managers and human resource professionals who use  social networking sites to research job applicants is between  % and  %

(d)

Suppose that the researchers wanted to estimate the proportion of hiring managers and human resource professionals to within mean reaction time to within 1% (Round your answer up to the nearest whole number.)
