A survey asked, "How many tattoos do you currently have on your body?" Of the 1216 males surveyed, 191 responded that they had at least one tattoo. Of the 1019 females surveyed, 129 responded that they had at least one tattoo. Construct a 90 % 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.
