Annual average wind speed values over time measured for a residential area located at 27th latitude and 34th longitude are given in the Table. After checking the goodness-of-fit by Kolmogorov - Smirnov test among the normal and log-normal distributions with a significance level of 5%, estimate the wind speed with a probability of 90% by the most appropriate distribution.

Considering the data, answer the questions. (a) What is the sample size of the discharge values? (b) What is the minimum discharge value? (c) What is the maximum discharge value? (d) What is the average value of the sample? (e) Explain and discuss what kind of uncertainty is observed in this problem. (f) Plot a histogram of annual maximum discharges using a uniform increment discharge of 100 m/s. (g) Plot a histogram of fractions of observations of annual maximum discharges corresponding to (e). (h) What is the probability that annual maximum discharge values vary between 500 m/s and 1000 m/s? 93 94 95 96 97 98 99 100 Wind Speed (m/s) Q (m/s) 542.95 1980 385 1981 440.5 1982 826.4 1983 443.2 3.88 3.72 3.93 3.92 4.09 4.22 4.11 4.33 4.46 4.12 4.42 3.85 3.89 3.7 3.47 4.98 5.44 4.97 4.43 4.5 6.22 5.91 5.45 3.38 4.24 1984 550.9 3/3 1985 198.8 1986 678.4 1987 569.6 1988 464.8 719.44 1989 578.2 1990 567.4 1991 447 ...
