2. A manufacturer has developed a new fishing line, which the company claims has a mean breaking strength of 15 kg with a standard deviation of 0.5 kg. A sample of 50 lines will be used to test the hypothesis that u = 15 versus the alternative that µ < 15. We will reject the null hypothesis if x < 14.9 . Find the probability of committing a Type 1 Error.
