A survey asked, "How many tattoos do you currently have on your body?" Of the 12311231 males surveyed, 190190 responded that they had at least one tattoo. Of the 10671067 females surveyed, 143143 responded that they had at least one tattoo. Construct a 9090% 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 1p1 represent the proportion of males with tattoos and p 2p2 represent the proportion of females with tattoos. Find the 9090% confidence interval for p 1 minus p 2p1−p2.
