# EE380 Special Due: 4/29/2016, Project Spring 2016 hard copy, no late acceptance 1. Use N(0,1), N(l,4), N(S,9) and N(-5,16) to generate Chi-square...

hello i need help solving this attached statistic problems using matlab

can you please help or if you know anyone on here that could help could you please let me know!

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. Sign up to view the entire interaction
