Example 2: Testing H0: µ=50 vs. Ha: µ<50 This example mirrors example 1. Again, using the critical xbar method, the critical z-value is -1.645. From the equation you get -1.645=(critical xbar-50)/(5/6 ...

The theory of statistical inference in such models - hypothesis testing, estimation and confidence sets - is then presented within ... In the final chapter, the theory of adaptive inference in ...
