One question was, $"$Do you think that there will be an increase in the number of full$-$time employees at your company over the next $12$ months?" In the current survey, $236$ of $400$ executives answered Yes, while in a previous year survey, $172$ of $400$ executives had answered Yes. Provide a $95\%$ confidence interval estimate for the difference between the proportions at the two points in time. $($Use current year $$ previous year. Round your answer to four decimal places.$)$
