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. Assume the other countries in the range 29.45–38.45 have higher obesity than the United States.)
