A survey asked, "How many tattoos do you currently have on your body?" Of the 1209 males surveyed, 199 responded that they had at least one tattoo. Of the 1023 females surveyed, 142 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 least one tattoo. Interpret the interval. Let p, represent the proportion of males with tattoos and pP2 represent the proportion of females with tattoos. Find the 95% confidence interval for p, -P2- The lower bound is The upper bound is (Round to three decimal places as needed.)

![**Survey on Tattoo Prevalence: Confidence Interval Calculation**
A survey inquired, "How many tattoos do you currently have on your body?" Among the 1,209 males surveyed, 199 reported having at least one tattoo. From the 1,023 females surveyed, 142 reported having at least one tattoo. The task is to construct a 95% confidence interval to evaluate whether the proportion of males with at least one tattoo significantly differs from the proportion of females with at least one tattoo. Subsequently, this interval should be interpreted.
Let \( p_1 \) represent the proportion of males with tattoos, and \( p_2 \) represent the proportion of females with tattoos. The goal is to find the 95% confidence interval for \( p_1 - p_2 \).
- **The lower bound is:** [Input required]
- **The upper bound is:** [Input required]
