Question:

On what statistic do we base our decision and for what values of the statistic do we reject the null hypothesis if we have a random sample of size n = 10 and are using the signed- rank test at the 0.05 level of significance to test the null hypothesis µ = µ0 against the alternative hypothesis
(a) µ ≠ µ0;
(b) µ > µ0;
(c) µ < µ0?
