A manufacturer of sports equipment has developed a new synthetic fishing line that he claims has a mean breaking strength of 8 kilograms with a standard deviation of 0.5 kilogram. Test the hypothesis that µ = 8 kilograms against the alternative that µ ≠ 8 kilograms if a random sample of 50 lines is tested and found to have a mean breaking strength of 7.8 kilograms. Use α = 0.01 level of significance. (Illustrate the six (6) steps in hypothesis testing using the traditional method)
