Which statement about a confidence interval is true? O There is a 95% probability that the true proportion is this interval. O 95% of the time, the sample proportion and the true proportion will be the same. O The interval contains 95% of the true proportion. O 95% of intervals constructed this way will contain the true proportion. O There is a 95% chance that the sample proportion is in the interval.

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.

We wish to estimate what percent of adult residents in a certain county are parents. Out of 600 adult residents sampled, 150 had kids. Based on this, construct a 90% confidence interval for the proportion p of adult residents who are parents in this county. Express your answer in tri-inequality form. Give your answers as decimals, to three places. p Express the same answer using the point estimate and margin of error. Give your answers as decimals, to three places. K P= Submit Question

With 99% confidence, it can be said that the sample proportion of adults who say they have started paying bills online in the last year is between the endpoints of the given confidence interval. B. The endpoints of the given confidence interval show that adults pay bills online 99% of the time. C. With 99% confidence, it can be said that the population proportion of adults who say they have started paying bills online in the last year is between the endpoints of the given 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 3.5 to 4.1 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%. O B. The statement does not make sense. The probability the population mean is greater than the upper limit is 5% and the probability it is less than the lower limit is 5%, so the probability it does not is 5% + 5% = 10%. O C. 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…
A survey asked, "How many tattoos do you currently have on your body?" Of the 1233 males surveyed, 183 responded that they had at least one tattoo. Of the 1042 females surveyed, 139 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. C Let p₁ represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 95% confidence interval for p₁ -P2- The lower bound is The upper bound is (Round to three decimal places as needed.)
Debbie and Ethan are going to construct confidence intervals from the same simple random sample. Debbie's confidence interval will have a 98% confidence interval and Ethan's will have a 95% confidence interval. A. Which confidence interval, if there is a difference will have a larger margin of error? B. Which confidence interval is more likely to cover the population mean, if there is a difference I am using a Ti84 and need to know how to get the answer.
