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 Females 240 100 0.41667 Males 215 67 0.31163 Difference 0.10504 Null Hypothesis: P1 = P2 Alternative Hyp: P1 = P2 SE (difference) 0. 04526 Z (uncorrected) 2.22 P 0.0262 95% Confidence Interval of Difference 0. 01716 0 O P(females) - P(males) differs from 0 O P(females) - P(males) = 0
