When phage infect a bacterial cell, they typically have a temporal program of gene expression, i.e., they express particular genes at particular times. What are two regulatory mechanisms phage use to control their gene expression?

Please state clearly each mechanism and provide detail explanation.

According to the 2016 CCSSE data from about 430,000 community college   students nationwide, about 13.5% of students reported that they “often” or “very often” come to class without completing readings or assignments.

Are the results similar at community colleges in California? Specifically, let’s test the claim that California students are different. Use a 5% level of significance.

Suppose that the CCSSE is given in California to a random sample of 500 students and 10.5% report that they “often” or “very often” come to class without completing readings or assignments.

a) State the hypotheses in words and write a sentence to explain what p represents.

b)Verify that the normal model is a good fit for the distribution of sample proportions.

c) Test the claim by a significance test( 6-steps, show all calculations)

d)State your conclusion.

Assume that you’ve owned and operated a very successful elite seafood restaurant in a rather small strip mall for several years. A Red Lobster chain seafood restaurant is just about to open across the street from you in another strip mall. Explain how this may affect your total revenue, marginal revenue, marginal cost, and total cost. In other words what, if any, changes would you have to make to what, how, and how much you produce to remain competitive

1. Red Cross and American Blood Centers (ABC) are the major blood banks in the United States. Red Cross represents 47% of the market share and ABC represents 46% of the market share. This means the blood bank market is very close to a duopoly market structure. Both companies advertise aggressively. Construct a payoff matrix using the following information:

• If neither firm advertises, Red Cross and ABC both earn profits of $750 million a year.
• If both firms advertise, Red Cross and ABC both earn profits of $500 million a year.
• If Red Cross advertises and ABC doesn’t, Red Cross earns profits of $900 million and ABC earns profits of $400 million.
• If ABC advertises and Red Cross doesn’t, ABC earns profits of $900 million and Red Cross earns profits of $400 million.

Please use the information above to answer the following questions.

1. If Red Cross wants to maximize profit, will it advertise? Briefly explain.
2. Is there Nash equilibrium to this advertising game? If so, what is it?
3. What (if any) is the dominant strategy for each company?

Write the answers to and explain the following:

What action can the Federal Reserve take to reduce unemployment? What is the primary tool used by the Federal Reserve to accomplish the action you listed in part (a)? Explain in detail how this tool works. Assuming the economy is currently operating at the natural rate of unemployment, what effect will the action you listed in part (a) have in the short-run on: output, price level, and interest rates. Use the AS/AD (Aggregate Supply / Aggregate Demand) and Money Market model to explain your answer.

Question 4 [40 Marks] You have seven mornings per week. On each morning, you can either study, go to the rock climbing wall, or sculpt (i.e., make sculptures). If you rock climb, you must be a member of the club. The membership fee is 100 Bobos each week. And, as member, you pay 10 Bobos for each morning of climbing. If you sculpt, you must rent a studio which costs 100 Bobos per month. Each morning you sculp, you use 10 Bobos worth of material.

[15 Marks] Your economics professor has asked you to produce a table showing your marginal cost for each of 7 mornings you might sculpt during a normal week. Your uncle, who has never taken economics, has asked you to explain the table and why the values you wrote down make sense. Provide your answers in sections labelled The Table and The Explanation

[10 Marks] Assume that in October, you rationally climbed two times per week and sculpted three times per week. In November, you know that the daily climbing price will be 5 bobo per morning. Explain, using the costs and benefits of sculping, how you will decide whether to rent a studio in November. Provide your answer in a section labelled November

[9 Marks] Assume that in March you rationally climbed two times per week and sculpted three times per week. A climber from out of town is willing to pay you 50 Bobos per week for your April membership. If you sell, you cannot climb. If this is the only change the professor is aware of, what does your economics professor predict about how often you sculp in April? Explain. Provide your answer in a section labelled April

[6 Marks] Assume that the following March, you rationally climbed two times per week and sculpted three times per week. In April the membership fee for the climbing club will increase 150 bobos per week. If this is the only change the professor is aware of, what does your economics professor predict about how often you sculp in April? Explain. Provide your answer in a section labelled April, redux
