Describe how to use the sign test to form a coefficient 1− α0 confidence interval for the median θ of an unknown distribution. Use the data in Exercise 7 in Sec. 8.5 to construct the observed coefficient 0.95 confidence interval. For which values of θ0 would you fail to reject the null hypothesis H0 : θ = θ0 at level of significance α0? |
