In a past General Social Survey, a random sample of men and women answered the question “Are you a member of any sports clubs?” Based on the sample data, 95% confidence intervals for the population proportion who would answer “yes” are .13 to .19 for women and .247 to .33 for men. Based on these results, you can reasonably conclude that

#Section 3: Mathematics and Quantitative Ecology
  1. At least 25% of American men and American women belong to sports clubs.
  2. At least 16% of American women belong to sports clubs.
  3. There is a difference between the proportions of American men and American women who
    belong to sports clubs.
  4. There is no conclusive evidence of a gender difference in the proportion belonging to sports clubs.

#Section 2: Evolution

A graph shows the frequency distribution of the character (body size). B graph shows the relation between body size and fitness, within one generation, and the third the expected change in the average for the character over many generations (if body size is inherited).
