A politician claims that she will receive at least 59% of the vote in an upcoming election.
The results of a properly designed random sample of 100 voters showed that 51 of those
sampled will vote for her. Is it likely that her assertion is correct at the 0.05 level of
significance?
(a) State the appropriate null and alternative hypotheses.
Ho: P
0.59
Ha: P
0.59
(ii) Find z. (Round your answer to two decimal places.)
(iii) Find the p-value. (Round your answer to four decimal places.)
(b) State the appropriate conclusion.
Reject the null hypothesis, there is not significant evidence that she will receive less than
59% of the vote. Fail to reject the null hypothesis, there is significant evidence that she
will receive less than 59% of the vote.
Fail to reject the null hypothesis, there is not
significant evidence that she will receive less than 59% of the vote.
