In a recent household telephone survey of 2,810 adults in a certain country, 27% reported that they own at least one gun. The researchers want to estimate the true percentage of adults in that country that own at least one gun. Complete parts a through f below. a. Identify the population of interest to the researchers. Choose the correct answer below. O A. The set of adults in the country that own a gun O B. The set of all gun ownership status (yeso) values for all adults in the country O C. The set of adults that responded to the survey D. The set of guns in the country b. Identify the parameter of interest to the researchers. The parameter of interest is c. Compute an estimate of the population parameter. (Type an integer or a decimal.) d. Form a 99% confidence interval around the estimate. (Round to two decimal places as needed.) e. Interpret the confidence interval practically. Choose the correct answer below. O A. There is a 90% probability that the true proportion of gun owners is the mean of the interval. O B. One can be 909% confident the true proportion of gun owners is one of the end points of the above interval. O C. One can be 09% confident the true proportion of gun owners lies within the above interval. O D. One can be 909% confident the true proportion of gun owners lies at the mean of the above interval. f. Explain the meaning of the phrase "99% confident." Choose the correct answer below
