critical region results

7.3        Suppose, in Exercise 6.12, we conclude that 60% of the voters favor the gasoline sales tax if more than 214 but fewer than 266 voters in our sample favor it. Show that this new critical region results in a smaller value for α at the expense of increasing β.


 

6.14 A manufacturer has developed a new  fishing line, which the company claims has a mean breaking strength of 15 kilograms with a standard deviation   of

0.5 kilogram. To test the hypothesis that μ = 15 kilo- grams against the alternative that μ 15 kilograms, a random sample of 50 lines will be tested. The critical region is defined to be x¯     14.9.

(a)   Find the probability of committing a type I error when H0 is true.

(b)   Evaluate β for the alternatives μ = 14.8 and μ =

14.9 kilograms.
