Wave Data: The data collected is based on a comparison study between two different mooring methods to analyse the amount of electricity generated from using waves at sea. The difference between the two mooring methods is the effect of the bending stress in part of the device where Method 1 had cheaper components in the system. Both methods were applied to the same subjects and where the sample sea states are the same. The question of interest is whether the bending stress differs for the two mooring methods.

(a) Set up the null and alternative hypotheses for this problem.

(b) Use MINITAB to calculate the sample mean, sample standard deviation and test for Normality.

c) Statistically test at a 10% level of significance whether the two mooring methods are significantly different. Include a conclusion in your answer
