A survey asked, "How many tattoos do you currently have on your body?" Of the 1222 males surveyed, 182 responded that they had at least one tattoo. Of the 1015 females surveyed, 133 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. Let p, represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 90% confidence interval for p, - P2- The lower bound is The upper bound is (Round to three decimal places as needed.)
