A survey asked, "How many tattoos do you currently have on your body?" Of the 1205 males surveyed, 199 responded that they had at least one tattoo. Of the 1030 females surveyed, 127 responded that they had at least one tattoo. Construct a 99% 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 99% confidence interval for p1−p2. The lower bound is nothing. The upper bound is nothing. (Round to three decimal places as needed.)
