hello i need help solving this attached statistic problems using matlab

thank you!

Or at least can you explain what they want us to solve for

3. The range, r, of a cannon projec tile under the influence of gravity, g=9.81 m/s 2, and fired with muzzle velocity = 10 rn/s is determined by the angle its barrel makes with the ground, {J. From your Physics classes you will recall that the range is calculated as: r({J) = 2(vo )2 jg sin{) costii} , If a wind of velocity 2 m/s 2/ blows against the project, what will be the r({J)? Assuming that {J is a random variable uniformly dis tributed between O and rr/2, 2. A stock broker makes a deal with a client that the client will pay the broker a 20% "reward" of any profit the broker makes for him, and will pay the broker nothing if the broker loses money for the client. The stock portfolio profit is a normal dis tribution with a mean of zero and a standard deviation of \$2. Use the resul ting histogram to calculate the expected value of the reward. (Note that has a Gaussian distribution with mean and standard devia tion can be generated using the "randn" function in MATLAB as following: NOTE 2.A random variable x= randn "c + µ ) 5 4 2 1 0 I I I I ;- - ; J 0.02 ---- 0.08 f(x)h2, u=0,1,2,. sigma=2 1. Use N(0,1), N(l,4), N(S,9) and N(-5,16) to generate Chi-square distribution (degree of freedom :4). Following is an example of Chi-square pdf with the sigma has different value of 2 and the mean values vary from 0 to 4.
In repor t, you have to submit your code and the resul ts (graphics). -=::::::}= wind direction l l generate the probabili ty density of the range f( r), through stochastic modeling. Use the resulting his togram to calculate the mean range of the projectile.
