Relate aggregates, concrete, asphalt, cement materials individually, and relate each material to the other materials. For example, how do they relate to a concrete or asphalt mixture? The goal is to demonstrate a thorough understanding of each material and their relationships to each other. Focus on a discussion and the significance of individual material groupings (aggregates, concrete (including Modulus Of Elasticity), asphalt, and cement), and explain in detail their importance to quality concrete and asphalt mixtures. Talk aboutWhat, How, and Why.” Demonstrate a thorough understanding of each material.

2. Suppose you serve as an economist on the President’s Council of Economic Advisors (CEA), and the President has asked the CEA to inform him on potential policy responses to a recession the Country is currently experiencing. Your boss, the head of the CEA, feels it would be a good idea to explain both “models” of the macroeconomy to the President in some detail, and has asked you to write a response to the questions below in the most straightforward way possible: A. Which policy tool does the Federal Reserve use to conduct monetary policy most of the time? How would the Fed use this tool to fight a recession? Explain your answer. B. What is fiscal policy? What are the two ways for government to enact expansionary fiscal policy? Explain. C. Use a graph to illustrate why Keynesian Model economists believe monetary policy or fiscal policy can stimulate economic growth in both the short and long run. (HINT: Your graph should show short run equilibrium output changing as a result of the government’s action.) D. What is the Keynesian model concept of the “multiplier”? Discuss the logic behind the Keynesian multiplier, and identify the fiscal policy action that will create the largest multiplier effect. E. Why do Classical economists believe that fiscal policy is not just ineffective, but actually harmful to the economy? F. Why do Classical Model economists believe that monetary policy is ineffective and potentially harmful to the economy? Give at least one reason (We discussed two reasons, bonus possible if you can correctly give/explain both).

A group of Brigham Young University—Idaho students (Matthew Herring, Nathan Spencer, Mark Walker, and Mark Steiner) collected data in November 2005 on the speed of vehicles traveling through a construction zone on a state highway, where the posted speed was 25 mph. The recorded speed (in mph) of 15 randomly selected vehicles is given below. Assume speeds are approximately normally distributed with σ=5.95 and that the average speed of drivers is about 5 mph over the limit, i.e. µ = 30.

20, 24, 27, 28, 29, 30, 32, 33, 33, 34, 36, 38, 39, 40, 40

  1. Describe the distribution of a single vehicle’s speed traveling through a construction zone (the population distribution).

  1. Describe the distribution of the mean speed of 15 vehicles traveling through a construction zone (the sampling distribution).

  1. Did you need to apply the Central Limit theorem in 2. above? Explain why or why not.

  1. What is the probability that a single vehicle will be traveling faster than 33 mph through the construction zone?

  1. What is the probability that the average speed of 15 vehicles is faster than 33 mph through the construction zone?

  1. Construct a 95% confidence interval for the true mean speed of drivers in this construction zone. Interpret the interval.

  1. Construct a 99% confidence interval for the true mean speed of drivers in this construction zone. Interpret the interval.
  1. Compare the widths of the 95% and 99% confidence intervals. Note which one is wider/narrower and explain why.

  1. Based on your intervals in 6. and 7., do you think that it is possible that the true average speed of all drivers is 25 mph (the actual speed limit)?

There is a rumor that most police officers will give some leeway in citations for speeding tickets of about 5 mph. Officers familiar with this construction zone have told you that they believe the average speed of drivers is 30 mph. We would like to use the sample above to test the notation that the mean speed of drivers is over 30 mph at the α = 0.05 level of significance. Use σ=5.95

  1. State the Null and Alternative hypothesis for this test of significance.
  1. Calculate the test statistic and interpret the result. (You may use your calculator to check this value, but for this problem you need to find this value “by hand” and show the work here.)

  1. State the P-value for this test of significance and provide a short explanation.

  1. Do we reject or fail to reject the Null Hypothesis? Write a complete statement here as modeled in your notes.

  1. Is there sufficient evidence that the mean speed of drivers in the construction zone is over 30 mph? Again, write a complete statement here as modeled in your notes.
