A newspaper infographic titled "Social Media Jeopardizing Your Job?" summarized data from a survey of 1,850 recruiters and human resource professionals. The infographic indicated that 54% of the people surveyed had reconsidered a job candidate based on his or her social media profile. Assume that the sample is representative of the population of recruiters and human resource professionals in the United States. USE SALT (a) Use the given information to estimate the proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile using a 95% confidence interval. (Round your answers to three decimal places.) Give an interpretation of the interval in context. O We are 95% confident that the true proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile falls directly in the middle of this interval. O We are 95% confident that the true proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile falls within this interval. O There is a 95% chance that the true proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile falls directly in the middle of this interval. O We are 95% confident that the mean number of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile falls within this interval. O There is a 95% chance that the true proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile falls within this interval. Give an interpretation of the confidence level of 95%.

O There is a 95% chance that the true proportion of recruiters and human resource professionals who have reconsidered a job candidate based on his or her social media profile falls within this interval. Give an interpretation of the confidence level of 95%. O Of all possible random samples, 95% would result in an interval that is centered at the actual value of the population proportion. O of all possible random samples, 5% would result in an interval that includes the actual value of the population proportion. O of all possible random samples, 95% would result in an interval that lies below the actual value of the population proportion. O of all possible random samples, 95% would result in an interval that includes the actual value of the population proportion. O Of all possible random samples, 5% would result in an interval that lies above the actual value of the population proportion. (b) Would a 90% confidence interval be wider or narrower than the 95% confidence interval from part (a)? O wider O narrower
