In a survey of 400 likely voters, 216 responded that they would vote for the incumbent and 184 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.

Using the survey results, the estimated value of

ModifyingAbove p with caret is 0.54(Round your response to four decimal places.)

Using Modifying Above p with caret (1minusModifyingAbove p with caret)/n as the estimator of the variance of ModifyingAbove p with caret the standard error of the estimator is 0.0249 (Round your response to four decimal places.)

The p-value for the test Upper H Subscript o Baseline : p equals 0.5 versus Upper H 1 : p not equals 0.5

is (Round your response to three decimal places.)

The p-value for the test Upper H Subscript o Baseline : p equals 0.5 versus Upper H 1 : p greater than 0.5

is(Round your response to three decimal places.)
