Using that information (n, point estimate for p), contract a 95% confidence interval. State what the variables are (n, p, critical value z, and E).

Data: Researchers from the College of Natural and Health Sciences for the University of Tampa surveyed 1,900 adults and found that 69% (the average result of 71% female and 67% male) of respondents thought they find people with dark hair more attractive.

So, n = 1,900, and p-hat (point estimation of population proportion) is 0.69. This means that q-hat is 1 - 0.69 = 0.31
