A survey asked, "How many tattoos do you currently have on your body?" Of the 1243 males surveyed, 188 responded that they had at least one tattoo. Of the 1028 females surveyed, 133 responded that they had at least one tattoo. Construct a 95% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval.
Let p1 represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 95% confidence interval for p1 - p2.
