Weibull distribution: From an analysis of wind speed data (hourly interval average, taken over a 1 year period), the Weibull parameters are determined to be c = 6 m/s and k = 1.8 at a potential WT site.

a. Estimate the number of hours per year that the wind speed will be between uB = 6.5 and uA = 7.5 m/s during the year.
b. Estimate the number of hours per year that the wind speed is above 16 m/s.
