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.  

3) (25 points) Consider the network set-up in Problem 2, but now suppose we want to upload the file of size F bit from the client C to the server S. That is, the direction of transmission is: Client  =>  Access link RC = R bit/s  => Backbone link RB2 = 10R  => Backbone link RB1 = 5R  =>  Access link RS = 2R  => Server. Drawing a labeled separate space-time diagram for each of the following parts a), b), and c) is required in order to receive credit. a) Suppose message switching is used, i.e., the entire file is treated as one large packet. How long does it take to upload the file? b) Suppose the file is broken up into packets, each packet with P information bits, and packet switching is used. Header bits are negligible. How long does it take to upload the file? c) Suppose circuit switching is used. The circuit that we set up across all the network links has a circuit transmission bit rate of R/2 bit/s. Assuming ts seconds set up time, how long does it take to upload the file?

How is determinism related to predictability?

Carl Rogers discussed in his person-centered therapy approach, the use of __________ (fill in the blank) where the therapist is nonjudgmental of the patient and warmly accepts them without placing stipulations on the acceptance.

What type of protein fiber, commonly found in the extracellular matrix, is extensible (can be stretched or extended)?

All four types of macromolecules essential to life are assembled from their simpler building blocks by removal of water.
