A newspaper infographic titled "Social Media Jeopardizing Your Job?" summarized data from a survey of 1,815 recruiters and human resource professionals. The infographic indicated that 51% 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.
(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. (Use a table or technology. Round your answers to three decimal places.)
Give an interpretation of the interval in context.
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.
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.
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.
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.
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.
Give an interpretation of the confidence level of 95%.
Of all possible random samples, 5% would result in an interval that includes the actual value of the population proportion.
Of all possible random samples, 95% would result in an interval that includes the actual value of the population proportion.
Of all possible random samples, 95% would result in an interval that lies below the actual value of the population proportion.
Of all possible random samples, 95% would result in an interval that is centered at the actual value of the population proportion.
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)?
wider
