International experience around the world is important in our culture of globalization. According to NAFSA, 54.5% of all American students traveling abroad went to Europe in the 2014-2015 academic year. To determine if there is shift in the proportion of students traveling to Europe, suppose a random sample of 300 students who had studied abroad was taken for the 2015-2016 school year. One-hundred sixty of the students traveled to Europe. a. Conduct a test to determine if the proportion of students traveling to Europe has changed. Be sure to provide a complete write-up. b. Based on the hypothesis test, would you expect 0.545 to be in confidence interval for the proportion? Explain without constructing the interval.

The most obese countries in the world have obesity rates that range from 11.4% to 74.6%. This data is summarized in the following table. Percent of Population Obese Number of Countries 11.4–20.45 32 20.45–29.45 11 29.45–38.45 5 38.45–47.45 0 47.45–56.45 3 56.45–65.45 2 65.45–74.45 1 74.45–83.45 1 (a) What is the best estimate of the average obesity percentage for these countries? (Round your answer to two decimal places.)(b) The United States has an average obesity rate of 33.9%. Is this rate above average or below? (Round your answers to two decimal places.) Since the average for the United Sates is 33.9%, compared to the average obesity rate of %, the United States has an obesity rate % higher than average. (c) How does the United States compare to other countries? (Assume that the United States is included in the data.
