A Deloitte employment survey asked a sample of human resource executives how their company planned to change its workforce over the next 12 months. A categorical response variable showed three options: the company plans to hire and add to the number of employees, the company plans no change in the number of employees, or the company plans to lay off and reduce the number of employees. Another categorical variable indicated if the company was private or public. Sample data for 180 companies are summarized as follows.

1) Conduct a test of independence to determine if the employment plan for the next 12 months is independent of the type of company.

-State the null and alternative hypotheses.

-Find the value of the test statistic.

-Find the p-value.

2) At a 0.05 level of significance, what is your conclusion?

A)Reject H₀. We conclude that the employment plan is independent of the type of company.

b)Do not reject H₀. We cannot conclude that the employment plan and the type of company are not independent.   

c) Reject H₀. We conclude that the employment plan is not independent of the type of company.

d)Do not reject H₀. We cannot conclude that the employment plan and the type of company are independent.

3)Discuss any differences in the employment plans for private and public companies over the next 12 months. (Round your numeric answers to two decimal places.

A)Employment opportunities look to be about the same for both public and private companies, with high proportions of "no change" and "lay off employees" planned for both.

b)Employment opportunities look to be about the same for both public and private companies, with high proportions of "add employees" planned for both.    

c)Employment opportunities look to be much better for private companies, while public companies have the greater proportions of "no change" and "lay off employees" planned.

d)Employment opportunities look to be much better for public companies, while private companies have the greater proportions of "no change" and "lay off employees" planned.

You studied a small, isolated human population and identified a new gene A. You found these numbers of individuals with these genotypes (capital letter represents dominance): 250 individuals of AA genotype, 500 individuals of Aa phenotypes and only 1 aa genotype, who is a 3 years old boy. Is gene A in Hardy-Weinberg equilibrium? Describe the possible reasons why gene A is (or isn’t) at HardWeinberg equilibrium. What can you conclude from the collected data?

Human Resources department at a manufacturing company is concerned about unauthorized absences of its employees. As a part of their research, they decided to investigate the relationship between the number of unauthorized days that employees are absent per year and the distance (miles) between home and work for the employees. A sample of 10 employees was chosen, and the following data were collected. Perform an appropriate analysis on the data at a 0.01 level of significance. Answer the following questions in the boxes below. Problem 1a) State clearly what the independent and dependent variables are in the problem. Problem 1b) Develop a scatter diagram. Based on the scatter diagram developed, do you expect a relationship between the variables? Indicate the expected relationship type if any. Problem 1c) Write down the estimated regression equation (use variable names along with coefficients and not just x and y).

The human body contains about 10^(14) cells, and the diameter of a typical cell is about 10 micrometers. Like all ordinary matter, cells are made of atoms; a typical atomic diameter is 0.1 nanometers. I have all of the correct answers, but I do not know how to get to these answers or solve them on my own. I would like to get explanations (why?) and see how it should be done (math being done). a) How does the number of atoms in a cell compare with the number of cells in the body? The answer is "should be the same". b) The volume of the cell is about The answer is 10^(-15) m^3. c) The mass of the cell is about The answer is 10^(-12) kg. d) The number of atoms in the body is closest to The answer is 10^(30). Thanks.

In 1783, the French physicist Jacques Charles supervised and took part in the first human flight in a hydrogen balloon. Such balloons rely on the low density of hydrogen relative to air for their buoyancy. In Charles’s balloon ascent, the hydrogen was produced (together with iron(II) sulfate) from the reaction of aqueous sulfuric acid on iron filings. (a) Write a balanced chemical equation for this reaction. (b) What volume of hydrogen is produced at 300 K and a pressure of 1.0 atm when 300 kg sulfuric acid is consumed in this reaction? (c) What would be the radius of a spherical balloon filled by the gas in part (b)?

Multi-stage flash distillation is used to desalinate seawater so it is fit for human consumption. A flash distillation tank is composed of small chambers (called "stages"), each at a lower pressure than the previous stage. Salt water enters the first chamber, some fresh water flash evaporates, condenses, and is removed from the distillation tank. The remaining salt water moves to the next chamber, some fresh water flash evaporates, condenses, and is removed from the distillation tank. The remaining salt water moves to the next chamber, and the process repeats until very salty water is expelled as waste. Brine that is 35,000 ppm salt is desalinated through a 5-stage flash distillation process. The pressure in the stages is such that 8% by mass of the water entering the stage evaporates and leaves as fresh water. If the desalination plant wants to produce 2800.0 gallons of drinking water per day, how many gallons of brine must the plant take in per day? The density of fresh water is 1.000 g/cm3. The density of brine is 1.025 g/cm3. a. What mass of waste brine is expelled in one day?

Dogs can be trained to detect diseases in humans by sniffing certain human secretions. In 54 trials, a sniffer dog was presented with 7 vials of secretions (6 from healthy individuals, 1 from a person with a disease). In 14 out of the 54 trials, the sniffer dog correctly identified the vial from the person with the disease. The test is judged to be useless if the dogs are essentially guessing, but there is some hope for improvement if the dogs react in some way that suggests that they are not guessing.

10) [6 marks] The population consists of all possible trials of this kind that this dog could be submitted to. What would be the parameter and random variable associated with each trial?

11) [6 marks] State the hypotheses for the trial that could be used to see if there was evidence that the dog was not guessing.

12) [10 marks] If the null hypothesis is true, then find the p-value for this test. You will need to use one of the following probabilities to do this: P[6 or more correct identifications] = 0.802 P[6 or fewer correct identifications] = 0.332 P[14 or more correct identifications] = 0.0173 P[14 or fewer correct identifications] = 0.9827

13) [5 marks] At a level of 0.1, is there evidence that the null hypothesis should be rejected? Explain, briefly. [Note: if you were unable to get a value from the previous question, assume that the p-value was 0.145].

14) [25 marks] State the meaning of the value 0.1 used as a significance level in this test, in the context of this question. I have a midterm monday, SOS

The human resources​ (HR) office is concerned that​ health-care costs differ among several​ departments: administration,​ clerical, manufacturing, information technology​ (IT), and sales. Staff selected a sample of 15 employees of each type and found health care costs for each. Complete parts​ (a) through​ (f). Assume alpha =0.1

Benzene is a known human carcinogen. The boiling point of benzene is 80. °C (reference 1).

a) Research online to find the short term exposure limit (STEL) for benzene. What does the STEL mean?

b) A friend is planning to do an experiment with liquid benzene at 21 °C on the open bench top in a small   (18 m3 ) poorly ventilated room (i.e. consider the room to be a closed system for this question). Convert the STEL to vapour pressure for this room.

c) Calculate the theoretical vapour pressure of benzene inside the room at 21 °C. Use your data to explain to your friend why he can or cannot do the experiment.

d) Fully explain why the following equation (derived from the ideal gas law) cannot be used to calculate the vapour pressure/temperature data at another temperature/pressure. P1/T1 = P2/T2

Thanks!
