A manufacturer of sports equipment has developed a new synthetic fishing line that he claims has a standard deviation of 0.5 kilogram. Test the hypothesis that p=8 kilograms against the alternative that p#8 kilograms if a random sample of 30 lines is tested and found to have a mean breaking strength of 7.8 kilograms. Use a 0.01 level of significance. Would you agree with his claim? A none of the choices B no, there is no sufficient evidence that the average breaking strength is equal to 8 kilograms. © yes, there is a sufficient evidence that the average breaking strength is equal to 8 kilograms.
