Question
In a survey of
400400
likely​ voters,
216216
responded that they would vote for the incumbent and
184184
responded that they would vote for the challenger. Let p denote the fraction of all likely voters who preferred the incumbent at the time of the​ survey, and let
ModifyingAbove p with caretp
be the fraction of survey respondents who preferred the incumbent.
 
Using the survey​ results, the estimated value of
ModifyingAbove p with caretp
is
0.54000.5400.
​(Round
your response to four decimal
places.​)
Part 2
Using
ModifyingAbove p with caretp​(1minus−ModifyingAbove p with caretp​)/n
as the estimator of the variance of
ModifyingAbove p with caretp​,
the standard error of the estimator is
0.02700.0270.
