Assume that matched pairs of data from a poll of Internet users who were asked if they make travel plans through the Internet result in 308 positive signs, 421 negative signs, and 30 ties when the value of the second variable is subtracted from the corresponding value of the first variable. Use the sign test with a 0.05 significance level to test the null hypothesis of no difference. Let , denote the median of the first variable and no denote the median of the second variable. What are the null and alternative hypotheses? OA H₂ H₁:₁₂ ⒸC. H₂:11₁=11₂ H₂:₁₂ Find the test statistic Test statistic = (Round to two decimal places s needed.) Find the P-value. P-value = (Round to four decimal places as needed.) Does the null hypothesis of no difference hold? OA. Since the P-value is greater than the significance level, reject the null hypothesis of no difference. B. Since the P-value is greater than the significance level, fail to reject the null hypothesis of no difference. OC. Since the P-value is less than the significance level, fail to reject the null hypothesis of no difference. OD. Since the P-value is less than the significance level, reject the null hypothesis of no difference. OB. H₂₁₂ H₂:1₁ 1₂ OD. H: ₂ H₂:1₁ 1₂
