I am interested in determining which sex, male or female, is more likely to have a tattoo. I collected data from 240 females and 215 males. 100 of the females and 67 of the males reported having at least one tattoo. I fed the data into Statistix and the following printout was produced.

Hypothesis Test - Two Proportions  Sample   Size  Successes  Proportion Males    215      67    0.31163 Females    240      85    0.35417 Difference              -0.04254 Null Hypothesis: p1 = p2 Alternative Hyp: p1  p2 SE (difference)  0.04429 Z (uncorrected)   -0.96  P  0.3368 95% Confidence Interval of Difference -0.12935 < p1-p2 < 0.04427
