For which of the following research designs would a matched pairs test be ideal? a) You have data on the mean income of residents in 45 different cities from the 2010 census and income information on the same cities in 2018 and you want to see if average incomes have increased from 2010 to 2018 b) You have data on how a random sample of voters plan to vote before the most recent debate, and how another random sample in the same area plan to vote after the debate and you want to see if the debate swayed voters c) A matched pairs test would be ideal in all of the situations d) You have data on the mean GPA of students participating in Greek Life at the U of A and students participating in Greek Life at Temple University and you want to see if Greek Life students at the two universities have different GPAs on average

Provide an informed opinion about Shake Shack’s future quarterly earnings in an appealing and convincing format. Concretely, you should:

• Gather information relevant for providing an informed opinion about Shake Shack’s EPS for the first quarter of 2020 (January-March).
• Filter and weigh the information according to relevance. Some information is more relevant than others. New information is more up-to-date than old information; information from reputable sources tends to be more reliable than information from laymen; information that contradicts what a majority of others believe may be flawed, etc.
• Provide a clear estimate of Shake Shack’s expected Q1 2020 EPS.
• Write 2 paragraphs in which you present your findings and your opinion (no PowerPoint or visual aids required).
• Motivate your opinions. Why do you think analysts’ estimates may be too high (Coronavirus?) or too low (overreaction to Coronavirus?)? Are some analysts’ forecasts made before the outbreak hit and restaurants closed?

Relaxing after work. The 2010 General Social Survey asked the question: "After an average work day, about how many hours do you have to relax or pursue activities that you enjoy?" to a random sample of 1130 Americans. A 93% confidence interval for the mean number of hours spent relaxing or pursuing activities they enjoy was [1.16, 1.84].

(a) Interpret this interval in context of the data: "There is a 93% chance that the average number of hours spent by Americans relaxing after an average day of work is between 1.16 hours and 1.84 hours."

(b) Suppose another set of researchers reported a confidence interval with a larger margin of error based on the same sample of 1130 Americans. How does their confidence level compare to the confidence level of the interval stated above? . Higher

(c) Suppose next year a new survey asking the same question is conducted, and this time the sample size is 2600. Assuming that the sampled standard deviation does not change, what will be the new margin of error of the 93% confidence interval constructed based on data from the new survey?

I have correctly answered a and b already. I just need help with C

In August 2010, Massachusetts enacted a 150-day right-to-cure period that mandates that lenders give homeowners who fall behind on their mortgage an extra five months to become current before beginning foreclosure proceedings. Policymakers claimed that the policy would result in a higher proportion of delinquent borrowers becoming current on their mortgages. To test this claim, researchers took a sample of 244 homeowners in danger of foreclosure in the time period surrounding the enactment of this law. Of the 100 who fell behind just before the law was enacted, 30 were able to avoid foreclosure, and of 144 who fell behind just after the law was enacted, 48 were able to avoid foreclosure. Let p₁and p₂ represent the proportion of delinquent borrowers who avoid foreclosure just before and just after the right-to-cure law is enacted, respectively. Which of the following is the appropriate test statistic value to analyze the claim at the 10% significance level?

• t₂₄₃ = −0.549

• z = 0.549

• t₂₄₃ = 0.549

• z = −0.549

5. The public debt - ownership

The following table contains approximate figures for gross domestic product (GDP) and the national debt in the United States for June 2001 and June 2010. The national debt represents the total amount of money owed by the federal government to holders of U.S. securities. All numbers are in trillions of dollars.

Source: “U.S. Treasury, Bureau of Economic Analysis.”

The net national debt is the portion of the national debt held outside the federal government (government agencies and the Federal Reserve System). In June 2001, the net national debt as a percentage of total national debt was  "50.3" "47.4" "50.8" "55.1" %?

In June 2001, the percentage of the U.S. national debt held by foreigners was "17.5" "18.9" " 18.0" "19.6" %?

The fraction of the national debt held by foreigners will eventually need to be repaid to foreigners, thereby reducing the collective purchasing power of Americans. Between 2001 and 2010, the fraction of the national debt held by foreigners "Decreased" or "Increased"

The absolute level of the debt does not necessarily provide a clear indication of a nation's debt burden. Thus, economists often look at relative measures of the national debt. One possible relative measure of the national debt is the net national debt as a percentage of GDP. In 2001, the net national debt was "26.7" "44.9" "49.7" "49.2" %   of GDP. Between 2001 and 2010, the net national debt as a percentage of GDP "Increased" or "Decreased"
