ANOVA

1. What type of experimental design is employed in this problem?

2. Identify the treatments and the dependent variable (Response).

3. Use a multiple boxplot in order to compare responses between different levels.

a. Are there differences between the mean of the responses in at least two of the levels?

b. Do you think this is the result of within-group variation or between-group variation?

4. State clearly the hypothesis that we are testing in this problem.

a. Set up the null and alternative.

5. Run ANOVA on the data and generate the output with plots.

a. Comment on the degree of freedom values for each source of variation. How do you calculate them?

b. Do we reject the hypothesis that we are testing? Why or why not?

i. If you reject, can you tell which level(s) is probably the one(s) that has the different mean? (Hint: use the boxplots from part 1a)

ii. If you are suspicious of only one level, repeat the ANOVA without that level and see if you fail to reject the null in the test.

b. Use the histogram of residuals to comment on the normality of error term (residuals) in this ANOVA model.

Now analyze the impact of the emergence of the coronavirus (Covid-19). Assume the epidemic significantly reduces the demand for meat only and that there are no changes to the supply of meat. On the same graph you produced in Question 1, graphically depict any changes in the marketplace and any changes that impact the individual firm. Show the movements of the curves (if any) and the new Short Run Equilibrium (SRE). Indicate the new market equilibrium P1 and Q1, the optimal output of an individual firm representative of the other firms in the industry at this SRE (labeled as q1), and the individual firm’s profit, if any (shaded and clearly labeled). Provide a brief narrative explaining the movements and the resulting change in an individual firm’s profit, if any. Please make sure you address the changes in the market equilibrium quantity Q, market price P, and the individual firm’s profit maximizing quantity q, if any. Reminder: be sure to label all relevant points and axes.

3. How did the followers of Buddha categorize his teachings?

Which of the following statements about the factor-price equalization theory and the effects of transportation costs are correct? Check all that apply.

Differences in transportation costs do not affect the comparative advantage of trading nations.

Differences in transportation costs across countries affect the volume and composition of trade.

A product will be traded internationally as long as the importing country is willing to pay more than the exporter’s cost to produce the good plus the cost to transport it.

Transportation costs and other trade barriers cannot prevent product prices from equalizing.

Which of the following statements about transportation costs are correct? Check all that apply.

Transportation costs are determined by the distance between two points, weight, size, value, and the volume of trade.

Over the past 50 years, transportation costs of U.S. imports have fallen to less than half of what they used to be, relative to the value of imports.

Transportation costs have recently become a larger expense for the global economy than was previously observed.

International transportation costs are declining everywhere in the world. Falling transportation costs reduce the volume of international trade by eliminating the basis for the growth of trade.

Calculate the final and initial mechanical energy for trials 1 through 6. Calculate the Diff %.

A block of mass m = 2.90 kg is pushed a distance d = 5.80 m along a frictionless horizontal table by a constant applied force of magnitude F = 16.0 N directed at an angle θ = 21.0° below the horizontal as shown in the figure below. (a) Determine the work done on the block by the applied force. J (b) Determine the work done on the block by the normal force exerted by the table. J (c) Determine the work done on the block by the force of gravity. J (d) Determine the work done by the net force on the block. J

How can the active learning strategy be applied to unsupervised learning and what if the oracle is not perfectly correct? How does the paper suggest?

How can yoy differentiate Slate from shale?

Deserted on a deserted Island you spot a slightly exposed tin can under a tree. Upon opening it you find it’s instructions to a treasure. It reads: “Ten paces from this very tree in a direction twenty degrees south of west lies the first location. Ten paces from this very tree in a direction sixty degrees north of east lie the second location. Walk from this tree exactly the distance and direction you would walk from the first location to the second location and you will find ye treasure. Yar” (a) What are the coordinates of treasure? (b) Use a physical representation in conjunction with the Related Quantities sense-making technique to check the validity of your answer.

4. Using the switching algebra theorems minimize the following logic functions:

a. F = WXYZ(WXYZ’ + WX’YZ + W’XYZ + WXY’Z)
b. F = XY + X’Y + YZ +Y’Z

c. F = A’C’ + A’BC + B’C
d. F = X + Y (Z + X + Z)

During the summer of 2017, fifteen former leaders of the White House Council of Economic Advisors signed a letter to President Trump urging him not to place tariffs on imports of steel into the United States. The letter notes that “Among us are Republicans and Democrats alike, and we have disagreements on a number of policy issues. But on some policies there is near universal agreement. One such issue is the harm of imposing tariffs on steel imports.” Tariffs are taxes imposed by government on imports. Those who endorse tariffs and other barriers to free international trade believe that such barriers protect domestic industries and the jobs of their employees.

Why do many economists, including those who have served for both Republican and Democratic administrations, support free trade policies and oppose tariffs and trade barriers even if these barriers are designed to protect domestic workers from losing their jobs? What types of jobs would be most vulnerable to job losses due to competition from imports?

1. Consider three point charges at the corners of a triangle as shown in the figure, where q1=6.0x10-9 C , q3= 5.0x10-9 C, q2=-2.0x10-9 C, and the distance of separation are shown in the figure. Calculate the resultant force acting on q3. (Given: 60degree angle at q1 & q2, radius= 5 meters)

please explain. Thank you :)
