Of the 1072 females surveyed, 147 responded that they had at least on 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. BELED Let p₁ represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find t 95% confidence interval for P₁-P2- The lower bound is The upper bound is (Round to three decimal places as needed.)
