A survey asked, "How many tattoos do you currently have on your body? Of the 1239 males surveyed, 186 responded that they had at least one tattoo. Of the 1064 females surveyed, 148 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...
