You recently sent out a survey to determine if the percentage of adults who use social media has changed from 63%, which was the percentage of adults who used social media five years ago. Of the 2763 people who responded to survey, 1735 stated that they currently use social media. a) Use the data from this survey to construct a 98% confidence interval estimate of the proportion of adults who use social media. Record the result below in the form of (#,#). Round your final answer to four decimal places.

Question

You recently sent out a survey to determine if the percentage of adults who use social media has changed from 63%, which was the percentage of adults who used social media five years ago. Of the 2763 people who responded to survey, 1735 stated that they currently use social media.

a) Use the data from this survey to construct a 98% confidence interval estimate of the proportion of adults who use social media. Record the result below in the form of (#,#). Round your final answer to four decimal places.

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
