A survey asked, How many tattoos do you currently have on your body?" Of the 1202 males surveyed, 188 responded that they had at least one tattoo. Of the 1027 females surveyed, 137 responded that they had at least one tattoo Construct a 99% 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 99% confidence interval for p, - P2 The lower bound is The upper bound is (Round to three decimal places as needed.) Interpret the interval. O A. There is 99% confidence that the difterence of the proportions is in the interval. Conclude that there is insufficient evidence of a significant difference in the proportion of males and females that have at least one tatto. OB. There is 99% contidence that the difference of the proportions is in the interval. Conclude that there is a significant difference in the proportion of males and females that have at least one tattoo OC. There is a 99% probability that the difference of the proportions is in the interval. Conclude that there is insufficient evidence of a significant difference in the proportion of males and females that have at least one tattoo OD. There is a 99% probability that the difference of the proportions is in the interval. Conclude that there is a significant difference in the proportion of males and females that have at least one tattoo
