A survey​ asked, "How many tattoos do you currently have on your​ body?" Of the 1238 males​ surveyed, 193 responded that they had at least one tattoo. Of the 1011 females​ surveyed, 136 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 p 1 represent the proportion of males with tattoos and p 2 represent the proportion of females with tattoos. Find the 95% confidence interval for p 1- p2.
