Parameter estimates:

intercept: 14179.871 3298.484 4.30 0.0003* (estimate Std Error tRatio Prob>t )

Baruch College has substantially less average debt compared to the other schools with similar in-state costs. Figure 10.13 contains JMP output for the simple linear regression of AveDebt on InCostAid with this case removed.

a) State the least-squares regression line.

b) The University of North Florida is one school in this sample. It has an in-state cost of $11,421 and average debt of $17,617. What is the residual?

c) Construct a 95% confidence interval for the slope. What does this interval tell you about the change in average debt for a $1000 change in the in-state cost?

ans:

a)    y = 0.7768753InCostAid+14179.871

b)   0.7768*11421+14179.871 = 23052.5628

residual = 23052.5628 – 17617 = 5435.562801

c) 0.7768753+- t*0.254022 = 0.7768753+- 2.073873*0.254022 =

  (0.2500659328, 1.303684667)

Baruch College was removed from this analysis because it was deemed an outlier. Let’s investigate its impact on the fit.

A) Refit the model using the entire sample of 25 schools. Create a table that summarizes the model estimates with and without this case.

B) Describe the impact this observation has on the fit of the linear regression model.

C) If you were writing a report for publication, would you include the fit with or without this case? Explain your answer.

INSTRUCTIONS: THERE ARE TWO SECTIONS IN THIS PAPER; SECTIONS A AND B
ANSWER ALL QUESTIONS IN SECTION A AND ONLY ONE IN SECTION B

SECTION A
QUESTION ONE.
In a given economy, the following hold true.
1.There are only two sectors-household and business sectors operating in the economy.
2. The percentage of every extra income which goes into consumption is 80%.
Given that an initial amount of 1000 currency units is introduced as investment in the economy. Draw up a table which tracks successive expenditure, income consumption and savings in the economy, up to the sixth round assuming the initial injection kicks in a multiplier process.
Using your table, calculate the total amount of income and consumption and deduce the value of the national income multiplier.
QUESTION TWO
Explain the difference between the criteria used to measure absolute and comparative cost advantages in international trade.
Assuming there are only two countries in the world, Oceania and Atlantis each having one resource unit which they use to produce either Cereals or Machine tools and the table below depicts the production possibilities of each country.

Maize (tons)
Machine Tools (Units)

You may believe that each day, married and unmarried women spend the same amount of time per week using Facebook. We would like to test this hypothesis. A random sample of 45 married women who use Facebook spent an average of 3.0 hours per week on this social media website. A random sample of 39 unmarried women who regularly use Facebook spent an average of 3.4 hours per week. Assume that the weekly Facebook time for married women has a population standard deviation of 1.2 hours, and the population standard deviation for unmarried Facebook users is 1.1 hours per week. Using the 0.05 significance level, do married and unmarried women differ in the amount of time per week spent on Facebook? State the decision rule for 0.05 significance level: H0: μ married = μ unmarried H1: μ married ≠ μ unmarried. (Negative values should be indicated by a minus sign. Round your answers to 3 decimal places.) Compute the test statistic. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.) What is the p-value? (Round your answer to 4 decimal places.) State your decision about the null hypothesis. Fail to reject H0 Reject H0
