You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly different from 0.21. You use a significance level of a = 0.005. Ho: p = 0.21 H:p / 0.21 You obtain a sample of size n = 456 in which there are 122 successes. What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value= The p-value is... O less than (or equal to) a O greater than a This p-value leads to a decision to... O reject the null O accept the null O fail to reject the null As such, the final conclusion is that... O There is sufficient evidence to warrant rejection of the claim that the proportion of voters who prefer Candidate A is different from 0.21. O There is not sufficient evidence to warrant rejection of the claim that the proportion of voters who prefer Candidate A is different from 0.21. O The sample data support the claim that the proportion of voters who prefer Candidate A is different from 0.21. O There is not sufficient sample evidence to support the claim that the proportion of voters who prefer Candidate A is different from 0.21.
