•If we fixnand the significance level↵, then we can determine the power function⇡(μ), the power as a functionof the alternative valueμ. An example of this function is shown in Figure 18.1.Exercise 18.2.If the alternative is less than, show that⇡(μ) =Φ✓-z↵-μ-μ0σ0/pn◆.Returning to the example with a model species and its mimic. For the plot of the power function forμ0= 10,σ0= 3, andn= 16observations,279
