A survey​ asked, "How many tattoos do you currently have on your​ body?" Of the 1238 males​ surveyed, 193 responded that they had at least one tattoo. Of the 1011 females​ surveyed, 136 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 at least one tattoo. Interpret the interval. Let p 1 represent the proportion of males with tattoos and p 2 represent the proportion of females with tattoos. Find the 95% confidence interval for p 1- p2.

A survey asked, "How many tattoos do you currently have on your body?" Of the 1203 males surveyed, 184 responded that they had at least one tattoo. Of the 1067 females surveyed, 133 responded that they had at least one tattoo. Construct a 99% confidence interval to judge whether the prope 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.)

A survey asked, "How many tattoos do you currently have on your body?" Of the 1217 males surveyed, 179 responded that they had at least one tattoo. Of the 1075 females surveyed, 137 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 p₁ represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 90% confidence interval for p₁-P2- The lower bound is The upper bound is (Round to three decimal places as needed.) Interpret the interval. OA. There is 90% 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. OB. There is a 90% probability that the difference of the proportions is in the interval.…

Social Networking Sites In a survey of 2255 randomly selected US adults (age 18 or older), 1787 of them use the Internet regularly. Of the Internet users, 1054 use a social networking site.7 Find and interpret a 95% confidence interval for each of the following proportions: (a)   Proportion of US adults who use the Internet regularly. (b)   Proportion of US adult Internet users who use a social networking site. (c)   Proportion of all US adults who use a social networking site. Use the confidence interval to estimate whether it is plausible that 50% of all US adults use a social networking site.
