Transcribed Image Text:According to an exit poll for an election, 53.7% of the sample size of 830 reported voting for a specific candidate. Is this enough evidence to predict who won? Test that the population proportion who
voted for this candidate was 0.50 against the alternative that it differed from 0.50. Use the Inference for a Proportion web app to complete parts a through d below.
The parameter is the number of voters that voted for the candidate.
D. The parameter is the sample proportion of votes for the candidate.
Define the notation for the parameter.
A. p = sample proportion of votes for the candidate
B. p= the number of voters that did not vote for the candidate
C. p= population proportion of voters that voted for the candidate
p = the number of voters that voted for the candidate
b. State the hypotheses and check the assumptions for a large-sample test. Choose the correct answer below.
O A. Ho: p=0.50; H₂: p0.50
The assumptions for a large-sample test are not met.
OB. Ho: p=0.50; H₂: p > 0.50
The assumptions for a large-sample test are met.
Ho: p=0.50; Ha: p < 0.50
The assumptions for a large-sample test are met.
D. Ho: p=0.50; H₂: p0.50
The assumptions for a large-sample test are met.
c. Report the test statistic and P-value and interpret the latter.
Z= (Round to two decimal places as needed.)
