1. You are given the task of creating a genetic map of three genes of Drosophila melanogaster . The genes are all located on the same chromosome. The genes are for body color, eye color and antenna formation. The alleles for body color are yellow and gray (wild-type), the alleles for eye color are sepia and red (wild-type) and the alleles for antenna are short and normal (wild-type). The mutant alleles for body and eye color are recessive, while the mutant allele for antenna formation is dominant. You follow the procedure for determining the order and map distance for the genes and obtain the following data:

Short, gray, sepia = 240 Short, yellow, red = 2 Short, yellow, sepia = 500 Short, gray, red = 22 Normal, yellow, red = 270 Normal, gray, sepia = 5 Normal, yellow, sepia = 15 Normal, gray, red = 444

Hints for drawings: size matters! Don’t draw all genes equidistant. If two genes are further away from each other than another set, make sure to draw it that way.

Based on the data given:

1. Define each gene and allele. Based on how you defined the alleles, what was the genotype and phenotype of the P gen? Make sure to notate alleles properly and to draw the chromosomes correctly. Make sure the genes are in the correct order.

2. What was the genotype and phenotype of the F1 gen? Make sure to notate alleles properly and to draw the chromosomes correctly. Make sure the genes are in the correct order.

3. What was the genotype and phenotype of the Test cross that was performed? Make sure to notate alleles properly and to draw the chromosomes correctly. Make sure the genes are in the correct order.

4. What are all of the map distances between the genes given? Make sure to draw the chromosomes correctly, the genes are in the proper order and units are used.

a. Please relate the "Storytelling with Data" principles on color, font, and overall visual design to financial model design. Please post thoughts on presentation and communication styles, whether text or graphics are more effective, and for which audiences this might be true.

Note: please consider:

- Which colors might be appropriate/inappropriate to use in corporate finance model building.
- How the principles translate into building models in Excel or Word for financial reporting purposes.

Please read the Visual and Statistical Thinking and explain what Edward Tufte means by these concluding words:

b. Visual representations of evidence should be governed by principles of reasoning about quantitative evidence. For information displays, design reasoning must correspond to scientific reasoning. Clear and precise seeing becomes as one with clear and precise thinking."

c. Please provide your understanding of 5 rules of data visualization

Your responses must be original and based on your own words.

Suppose you are about to begin a rafting trip through the Grand Canyon. A guide unrolls your inflatable raft on the grass next to the river and pumps air into the raft until it becomes nice and firm. The raft is then placed onto the cold water of the Colorado River and is anchored to a tree by a rope. A short time later you notice that the raft has lost its firmness and has become “baggy”. A whiner in your group cries “Oh no! There is a hole in our raft. I’m not going!” But you say “Don’t worry the raft lost its firmness because it was put in the cold water.”  Use the kinetic model to explain why the raft would lose its firmness. In your answer you should relate the kinetic model explanation for the changes in the movement of gas molecules to what happens to the temperature and number density of the air in the raft after being placed in the cold water.

You are a manager of a sales team that travels often. Your responsibility is to approve expenses accrued during the trip.

Your job is to draft a travel expense policy that covers what employees can or cannot expense. Please draft a document that covers the following:

1. Expense limits for transportation (air fair, taxi, parking), hotel, and meals.
2. Draft a section that discusses items that will not be covered as an acceptable expense

Your role. You are an international development consultant who has been contracted by a country to provide advice on a strategy to increase long-run economic growth. The country’s current economic state. The country is currently in a stable economic situation. It’s income per capita has been growing at an almost constant but low rate for the last 10 years. Growth rate as well as the level of income per capita has been significantly lower than in neighbouring similar countries, which has made the government wonder if it would be possible to increase the rate of growth in the years to come. The average household expenditure in consumption is larger than in neighbouring similar countries while the population growth rate and capital depreciation rate are approximately the same. Your task as a consultant. The government would like to increase the growth rate of income per capita in the coming years to achieve a level of income per capita in the long run that is comparable to neighbouring similar countries. Three prestigious political leaders of the country have recommended three different policies to achieve the government’s objective. Your task is to choose the right policy for the country using the Solow Model to substantiate the arguments in favour of your choice and the arguments against the other two policy options. Policy proposals

• Political leader 1: “The government should implement a policy to permanently increase the population growth rate by, for example, improving child-care services and providing social-security payments that increase significantly when families have an additional child”.

• Political leader 2: “The government should implement a policy to incentivise consumption, so the proportion of disposable income allocated to consumption increases permanently”.

• Political leader 3: “The government should implement a policy to incentivise the population to increase the saving rate, so the proportion of disposable income allocated to saving increases permanently”. Instructions. Assume the country’s economy is currently at steady state.

a. Indicate which policy option is the best strategy to achieve the country’s economic objectives.

b. Use the Solow Model without technology to explain your answer in point (a) above. Write your answer in no more than 200 words and use the Solow Diagram to illustrate.

c. Use the Solow Model without technology to explain why the other two policy options (the two policy options you did not choose in point (a) above) are not recommendable to achieve the government’s objective. Use the Solow Diagram to illustrate your argument against each of these two policies.

Of 200 girls 165 wanted to go to hill station for weekend. And of 210 186 boys preferred hill station. Using the .10 level of significance, can we conclude that there is a significant difference in the proportion of girls and the proportion of boys who preferred hill station?

A STAT 200 instructor wants to know if students tend to score differently on the lesson 4 and 5 quizzes. Data were collected from a representative sample of 60 students during the Summer 2018 semester. Data were paired by student. The mean difference, computed as Lesson 4 Quiz – Lesson 5 Quiz, was 0.3833 points with a standard deviation of 1.9891 points.

A. Explain why it is appropriate to use the t distribution to approximate the sampling distribution in this scenario.

B. In Minitab Express, conduct a paired means t test to determine if there is evidence that lesson 4 and 5 quiz scores are different in the population of all STAT 200 students. Use the five-step hypothesis testing procedure and remember to include all relevant Minitab Express output. Step 1: Check assumptions and write hypotheses Step 2: Calculate the test statistic Step 3: Determine the p value Step 4: Decide between the null and alternative hypotheses Step 5: State a “real world” conclusion

C. In Minitab Express, conduct a single sample mean t test given a sample size of 60, sample mean of 0.3833, and sample standard deviation of 1.9891 to determine if there is evidence that the population mean is different from 0. Use the five-step hypothesis testing procedure and remember to include all relevant Minitab Express output. Step 1: Check assumptions and write hypotheses Step 2: Calculate the test statistic Step 3: Determine the p value Step 4: Decide between the null and alternative hypotheses Step 5: State a “real world” conclusion

D. Explain why your test statistic and p value were the same in parts B and C. E. What minimum sample size would be necessary to construct a 95% confidence interval for the mean difference in lesson 4 and 5 quiz scores with a margin of error of 0.20 points?

answer the following question :

1. Say we live in another galaxy. We observe the galaxy's globular clusters and they appear to be uniformly spread out in all directions. What would this tell us about where we are in the galaxy and why?

2. Why do we think that large elliptical galaxies result from the merger of spiral galaxies?

3. You are in a windowless box. You feel yourself pressed to the floor. What are the two things that could be causing this? How does general relativity explain this? What would an outside observer notice about your watch?
