A news article that you read stated that 58% of voters prefer the Democratic candidate. You think that the actual percent is smaller. 150 of the 300 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.05 level of significance?   Interpret the p-value in the context of the study. If the population proportion of voters who prefer the Democratic candidate is 58% and if another 300 voters are surveyed then there would be a 0.25% chance fewer than 50% of the 300 voters surveyed prefer the Democratic candidate. If the sample proportion of voters who prefer the Democratic candidate is 50% and if another 300 voters are surveyed then there would be a 0.25% chance of concluding that fewer than 58% of all voters surveyed prefer the Democratic candidate.  There is a 58% chance of a Type I error. There is a 0.25% chance that fewer than 58% of all voters prefer the Democratic candidate. Interpret the level of significance in the context of…

Suppose 242 subjects are treated with a drug that is used to treat pain and 50 of them developed nausea. Use a 0.01 significance level to test the claim that more than 20% of users develop nausea. O A. Ho:p=0.20 H;:p>0.20 O B. Ho: p= 0.20 H,:p#0.20 OC. Ho: p=0.20 H4:p0.20 H4:p= 0.20 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Fail to reject Ho. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. O B. Reject Ho. There is sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. O C. Reject Ho. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. O D. Fail to reject…
