Define confidence interval and degree of confidence. Provide at least one example of a confidence interval and interpret the result.

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 Surprising fact indicates that a small proportion of teens use a password on their mobile device. A poll chooses a simple random sample of 120 teens and asks if they use a password on their mobile device. The results showed that 56 of teens in our  sample used a password on their mobile device. Find a 90 % confidence interval for the proportion of teens who use a password on their mobile device. Interpret your confidence interval.

Determine whether the statement below makes sense or does not make sense. Explain clearly. Based on our sample, the 95% confidence interval for the mean amount of television watched by adults in a nation is 3.1 to 4.5 hours per day. Therefore, there is 95% chance that the mean for all adults in the nation will fall somewhere in this range and a 5% chance that it will not. Choose the correct answer below. O A. The statement makes sense. There is 95% probability that the confidence interval limits actually contain the true value of the population mean, so the probability it does not fall in this range is 100% – 95% = 5%. %3D . O B. The statement makes sense. There is 5% probability that the confidence interval limits do not contain the true value of the sample mean, so the probability it does not contain the true value of the population mean is also 5%. O C. The statement does not make sense. The probability the population mean is greater than the upper limit is 5% and the probability it…
