Q1- An article in the Journal of the Indian Geophysical Union titled "Weibull and Gamma Distributions for Wave Parameter Predictions" (2005, Vol. 9, pp. 55-64) used the Weibull distribution to model ocean wave heights. Assume that the mean wave height at the observation station is 2.5 m and the shape parameter equals 2. Determine the standard deviation of wave height.Solve using numerical solutions.
