Question

Assume that matched pairs of data result in the given the number of signs when the second variable is subtracted from the corresponding value of the first variable. Use the sign test with a 0.05 significance to test the null hypothesis of no difference. Positive signs: 15; negative signs: 7; ties: 1 Is there sufficient evidence to reject the null hypothesis of no difference? Yes, because the test statistic is greater than the critical value. No, because the test statistic is greater than the critical value. Yes, because the test statistic is less than or equal to the critical value. No, because the test statistic is less than or equal to the critical value.
