You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly more than 0.37. You use a significance level of o: = 0.05. Hg:p = 0.37 H113) :3" 0.37 You obtain a sample of size n = 549 in which there are 222 successes. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? [Report answer accurate to four decimal places.) p-value = The p-value is... '13:? less than [or equal to) a: '13:? greater than or This test statistic leads to a decision to... '33:} reject the null '3' accept the null '3' fail to reject the null As such, the final conclusion is that...
