Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 36 of the 43 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 95 of the 109 subjects developed rhinovirus infections. Use a 0.01 significance level to test the claim that echinacea has an effect on rhinovirus infections.

Complete parts (a) through (c) below.

a) Conduct an appropriate Hypothesis Test using  = 0.01 level of significance to determine if echinacea has an effect on rhinovirus infections. Include a conclusion that is in terms of the problem. 1. (2 pts.) State the Hypothesis: ?0: ?1:

2. (1 pt.) Determine the P-value.

3. (3 pts.) State your decision.

4. (4 pts.) State your conclusion in terms of the problem scenario. b)

Construct a 95% confidence interval to test the claim. Does the confidence interval agree with the conclusion of the hypothesis test? (You only need to include the confidence interval obtained from STATCrunch or Calculator) Explain your answer.

Warren INC. bases their cost of capital or WACC on a number of erroneous assumptions.Going by their current methodology, Warren’s wacc is:

Compute/answer the following:

1.Look at the pre-tax cost of each component in the current wacc shown above. What is the problem with these three values? In other words, if you knew nothing about how Warren is computing its wacc, and were only shown those three values, what red flag should these numbers raise?

2.Provide a revised estimate of Warren’s wacc using methods revised weighted average cost of capital. Show all of your work in putting together your estimate of the wacc. Also, you will have to make choices, so where needed,describe the choices/assumptions that you made in estimating the wacc.

3. With the old wacc estimate above, and your new wacc estimate, describe the impact on (1) the value of the firm, (2) investment decisions, and (3) growth of using the new wacc as opposed to the original wacc.

4.Should Warren use the new wacc for all potential investments/projects? Why/why not?

The eye has a focal length of about 25 mm, and the visible spectrum extends from 390 nm (violet) to 750 nm (red). Note that the light-sensitive cells on the retina have radii ranging from 0.75 μm to 3.0 μm. What smallest Airy disk radius is possible for the eye?
