# Question

Rework Exercise 16.20 with the level of significance changed to 0.01.

In exercise

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?
