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 kilograms. To test the hypothesis that μ=15 kilograms against the alternative hypothesis that μ<15 kilograms, a random sample of 50 lines will be tested. The critical region is defined to be when the sample mean is less than 14.9 kilograms.
a) Find the probability of committing a type 1 error when H˳ is true
b) Evaluate β (Beta) when μₐ =14.8 and μₐ =14.9 kilograms
