3. Suppose you are thinking of investing $100,000 in stock indexes. You are currently considering investing either in the financial sector or the technolgy sector but the returns will depend on the state of the economy. The following table summarizes the estimated net profts that would be realized during the next two years for each of the two investment alternatives you are considering.

1. What decision would maximize expected profit for you? Show the necessary steps.
2. What is the maximum amount you should be willing to pay for a perfect forecast of the state of the economy? Show the necessary steps.                    

1. Since perfect forecast of the state of the economy is impossible suppose you are considering hiring a financial analyst to help you forecast the state of the economy for the next two years. In the past the analyst accurately predicted a good economy 92% of the time. The analyst also has a history of incorrectly predicting a poor economy 20% of the time. She charges $10,000 for the forecasting service. Please calculate the expected value of survey information (EVSI) for the financial analyst you are considering hiring and briefly explain what your result means. Given your results will you hire the financial analyst? Please justify your answer and show all the necessary steps. Also calculate the efficiency of the financial analyst and explain what it means.                                                                                 

In lab you are going to be using drosophila flies with sepia mutations (SE, se) causing brown eyes found on chromosome 3 and apterous mutation (AP, ap) on chromosome 2 causing loss of wings. These are recessive mutations. Red eye is the wild-type phenotype. Assuming you have a female heterozygous at both loci. Draw the chromosomes as they go through meiosis (Make sure you show somatic cell, prophase I, metaphase I, metaphase II, gametes.) Draw all possible gametes. What percentage of each phenotype do you expect? What are all the possible phenotypes and genotypes would you expect? This female mates with a male that is also heterozygous at both loci and they have 1000 progeny.

1. What are all possible phenotypes you could recover?

A. Red eyes and wings OR Red eyes and no wings

B. Red eyes and wings OR Brown eyes and no wings

C. Red eyes and wings OR Brown eyes and wings

D. Red eyes and wings OR Brown eyes and wings OR Red eyes and no wings

Word Answer:

A beam of white light is incident on the surface of a diamond at an angle ?a.(Figure 1) Since the index of refraction depends on the light's wavelength, the different colors that comprise white light will spread out as they pass through the diamond. The indices of refraction in diamond are nred=2.410 for red light and nblue=2.450 for blue light. The surrounding air has nair=1.000. Note that the angles in the figure are not to scale.

Part A

Calculate vred, the speed of red light in the diamond. To four significant figures, c=2.998×108m/s.

Express your answer in meters per second to four significant digits.

Part B

Calculate vblue, the speed of blue light in the diamond. To four significant figures, c=2.998×108m/s.

Express your answer in meters per second to four significant digit

Part C

Derive a formula for ?, the angle between the red and blue refracted rays in the diamond.

Express the angle in terms of nred, nblue, and ?a. Use nair=1. Remember that the proper way to enter the inverse sine of x in this case is asin(x)

Let’s say the average per capita annual health care cost for mid-size US-based corporations is $5,886. An organization competing for business has funded several health maintenance organizations (HMOs). A sample of their average annual costs per person is as follows:
