According to a survey, 1.22% of factory employees in a country suffered from job related stress.

Supposed 100 employees are selected at random. We are interested to find the number of employees amongst these 100 that suffers from job-related stress.

b.(i) State the assumptions needed so that the situation can be modelled as a binomial experiment.

(ii) Hence, find the probability that at most 2 out of these 100 employees suffers from job-related stress.

(iii) Calculate the mean and standard deviation for the number of employees amongst these 100 that suffers from job-related stress.   

Suppose we are interested to use Poisson approximation for the problem in part (b).

c.(i) State the assumptions needed so that binomial distribution can be approximated by the Poisson distribution.

(ii) Assume that number of employees that suffers from job-related stress has a Poisson distribution with a mean which is equal to the mean calculated in part (b)(iii). Hence, find the probability that at most 2 of these employees suffers from job-related stress.

(iii) Compare your answer in part (c)(ii) to your answer in part (b)(ii). Is the Poisson distribution a good approximation in this case? Explain. (Note that an error of 0.005 or less would indicate a good approximation.)

(d) Suppose we are interested to use normal approximation for the problem in part (b).

(i) State the assumptions needed so that binomial distribution can be approximated by the normal distribution.

(ii) Assume that number of employees that suffers from job-related stress has a normal distribution with mean and standard deviation which are equal to the mean and standard deviation calculated in part (b)(iii). Hence, find the probability that at most 2 of these employees suffers from job-related stress.

(iii) Compare your answer in part (d)(ii) to your answer in part (b)(ii). Is the normal distribution a good approximation in this case? Explain. (Note that an error of 0.005 or less would indicate a good approximation.)

The use of cellular phones in automobiles has increased dramatically in the last few years.

What is your conclusion from the following sample information? Use the 0.05 significance level.

Our discussion topic concerns the calculation of stock values using the Capital Asset Pricing Model (CAPM). Explain the CAPM model.Choose the firms J&j and Pepsi Co and discuss whether the betas are what you would expect. Be sure to explain why or why not. Calculate the returns based on the CAPM model. Be sure to state your assumptions.

The Weighted Average Cost of Capital (WACC) for a firm can be calculated or found through research. Select two firms in the same industry. The industry may be that in which you currently work or it may be an industry in which you are interested. Calculate or find the WACC for the two firms. How do the WACCs compare? Are the WACCs what you would expect? What causes the differences between the two firms' WACCs?

1. A “bed of nails” is a huge number of nails arranged in a piece of wood so that they all point up with the sharp points vertically upward. A person can lay down on the “bed of nails” and rest on these thousands of nails without pain or injury. Explain how this can occur.

2. A huge battleship is made of steel which has a density close to iron (almost ten times that of water) yet it can float. Explain why.

3. When a fluid flows through a constriction in a pipe, does the pressure in the fluid increase, decrease of remain constant. Explain your answer fully.

4. A large tank full of water has a nozzle which is open and water shots out of the nozzle vertically.

In a carnival game, a player spins a wheel that stops with the pointer on one (and only one) of three colors. The likelihood of the pointer landing on each color is as follows: 62 percent BLUE, 24 percent RED, and 14 percent GREEN.

Note: Your answers should be rounded to three decimal places.

(a) Suppose we spin the wheel, observe the color that the pointer stops on, and repeat the process until the pointer stops on BLUE. What is the probability that we will spin the wheel exactly three times?

(b) Suppose we spin the wheel, observe the color that the pointer stops on, and repeat the process until the pointer stops on RED. What is the probability that we will spin the wheel at least three times?

(c) Suppose we spin the wheel, observe the color that the pointer stops on, and repeat the process until the pointer stops on GREEN. What is the probability that we will spin the wheel 2 or fewer times?
