Annual maximum wind speed gusts have been modeled as both a Type I (Gumbel) and Type II largest extreme value. If the average maximum wind gust is 60 mph and the standard deviation is 12 mph, what is the probability that the annual maximum wind speed gust will exceed 90 mph for each model?

What is the probability that the max wind pressure will
exceed 30?
A large parabolic antenna is designed against wind load. Durng a wind storms, the maximum wind induced pressure on the antenna, P, is calculated as: 2 where C is the drag coefficient, R is the air mass density, V maximum wind speed, and P is the pressure. C, R, and V are statistically independent lognormal random variables with the...

451 In the United States, the mean and standard deviation of adult women's heights are 65 inches (5 feet 5 inches) and 3.5 inches, respectively. Suppose the American adult women's heights have a normal distribution. a. If a woman is selected at random in the United States, find the probability that she is taller than 5 feet 8 inches. b. Find the 72nd percentile of the distribution of heights of American women. c. If 100 women are selected at random...

2. A wind turbine has the maximum power output at the rated speed of 12 m/s and a rotor diameter of 82 meters. The cut-in and cut-out speeds for this type of wind turbine are 4 m/s and 23 m/s, respectively. The table below shows the annual wind data near a potential site for setting up a wind farm using this type of wind turbine and the power coefficient of the wind turbine at the specific wind speed. The air...

The mean annual inflation rate in the UNited States over the past 98 years in 3.37% and has a standard deviation of approx 5%. In 2018, the inflation rate was below 1.9%. If the annual inflation rate is normally distributed, what is the probability that inflation rate will be below 1.9% in 2019? Please show all work, including step by step.

Traffic police monitor the speed of vehicles as they travel over a new bridge. The average speed for a sample of 31 vehicles was 82.72 km/h, with the sample standard deviation being 4.61 km/h. We will assume that the speeds are Normally distributed, and the police are interested in the mean speed. Part a) Since the variance of the underlying Normal distribution is not known, inference here would involve the t distribution. How many degrees of freedom would the relevant...

Traffic police monitor the speed of vehicles as they travel over a new bridge. The average speed for a sample of 27 vehicles was 91.29 km/h, with the sample standard deviation being 4.94 km/h. We will assume that the speeds are Normally distributed, and the police are interested in the mean speed. Part a) Since the variance of the underlying Normal distribution is not known, inference here would involve the t distribution. How many degrees of freedom would the relevant...
