LO (b) A manufacturer of sports equipment has developed a new synthetic fishing line that is claimed to have a mean breaking strenght of 8 kg.

The sample had a mean breaking strength of 7.8 kg and a standard deviation of 0.5 kg. Write down your null hypothesis and alternative hypothesis and then, using an appropriate distribution, test your null hypothesis against your alternative hypothesis at the 5% significance level.
