Question
Transcribed Image Text:A survey asked, "How many tattoos do you currently have on your body?" Of the 1244 males surveyed, 189 responded that they had at least one tattoo. Of the 1016 females surveyed, 136 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 p, 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 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.
O B. There is 99% confidence 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.
O C. 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.
O D. 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.
