c. The United States per capita consumption was 316 million BTU. How many standard deviations from the mean was its consumption?

The solutions to Exercise 10.33 in the back of the book are wrong. The standard error in part a should be 1.78 (not 0.701) and the confidence interval should be (2.36, 9.44). With 95% confidence, we estimate that the mean body dissatisfaction assessment score is between 2.4 and 9.4 points higher for lean sport athletes compared to non-lean sport athletes.
