Suppose we compare GDP per person in Botswana and the United States in two ways: first using the nominal exchange rate and then again using the relative price-based conversion. The GDP per person in Botswana calculated using the exchange rate method is $500 while that calculated using the relative price-based conversion is $1,000. What is the relative price ratio between Botswana and the U.S. (i.e., the price level for Botswana relative to the United States)?  Round your answer to the nearest hundredth.

The following table contains observed and predicted GDP per capita numbers – all relative to the United States – for three different countries. You can assume that the three countries share the same capital income share . Select all the correct answers below. Observed GDP per capita Predicted GDP per capita China 0.30 0.80 Japan 0.70 0.95 Brazil 0.25 0.75

Compute this economy’s GDP per capita in the long run. Round your answer to the nearest tenth.

Suppose that nominal (and real) GDP in the United States was $1,000 in the year 1900. Assume that the US nominal GDP grows at a constant rate of 5.0% and the inflation rate is 2.0% per year (every year). Using the constant growth rule in equation (3.7) in the textbook plus the fact that

Patients who undergo chronic hemodialysis often experience severe anxiety. The accompanying data give score results from a psychiatric questionnaire for patients that viewed relaxation​ videotapes, where higher scores correspond to higher anxiety. Use limit grouping with a first class of 11–17 and a class width of 7.   *You will use the information from your distribution for the next two questions. Save your scratch work.    Obtain a frequency and relative frequency distribution.    (Type integers or decimals rounded to three decimal places as​ needed.) Anxiety Frequency Relative Frequency 11-17 [f1] [r1] 18-24 [f2] [r2] [c] – [d] [f3] [r3] [e] – [f] [f4] [r4] [g] – [h] [f5] [r5] [i] – [j]  [f6] [r6] [k] – [l] [f7] [r7] [m] – [n] [f8] [r8] [o] – [q] [f9] [r9]

Construct a dotplot for the given data. The following data represent the number of cars passing through a toll booth during a certain time period over a number of days. 38​, 39​, 37​, 37​, 44​, 38​, 41​, 38​, 39​, 35​, 42​, 39​, 43​, 37​, 41  

Please be aware that it is difficult to program answers for every possible calculation variation that the students may offer while still being “correct.”   For example, the exact answer rounded to three decimal places may be 0.781.  Students may still work the problem correctly, but round in their steps.  They may get 0.782 or 0.780 etc….  There may also be typos and spelling errors.   For these reasons, correct answers may be marked as incorrect initially.  I do review the tests and try to correct these errors.  Don’t panic until I have reviewed the tests.    

(5) The Dietary Guidelines for Americans (DGAs) are updated every five years, with the next update scheduled for 2025. The current DGAs there is no recommendation related to consumption of ultra-processed foods. Would you recommend this is added to the DGAs in 2025? Why or why not?  In writing your response, consider the debate recently highlighted in the American Journal of Clinical Nutrition.  Does the concept of ultra-processed foods inform dietary guidelines?

(1) A 2020 review by McCabe et. al. in the Journal of the Academy of Nutrition and Dietetics (120:1198-1209) discusses cultural competency in nutrition. This article concludes, “Cultural competence creates opportunities for growth and development of health professionals to serve diverse communities and work environments; future work should include standardizing evaluations of training, specifically to include both qualitative and quantitative methods.” The Program in Nutrition has also developed a Cultural Continuum. Discuss how to incorporate cultural awareness and thoughtfulness in both qualitative and quantitative research.  

(4) The ASA24 is an internet-based automated self-administered 24-hour dietary recall application developed by NCI. It uses technology drawn from the USDA’s Automated Multiple-Pass Method to provide a tool to researchers, educators, and the public for collecting multiple 24hr recalls. The ASA24 has become a very popular method of data collection given that it can be used free of charge to investigators that register their research studies.  Describe the strengths and limitations of the ASA24 recall method and discuss whether or not it has been shown to be valid in adults and children.
