Question
**Exercise on Uniform Distribution and Histograms**

Write a program to generate two independent and uniformly distributed random variables \( x_1 \) and \( x_2 \sim U(-1,1) \), each with 1000 realizations. 

(a) Use the histogram to verify the probability density function (pdf) of \( z = x_1 + x_2 \).

(b) What shape does the histogram of \( w = \frac{1}{\sigma} \sum_{i=1}^{10} \frac{x_i}{2} \) look like? Can you explain why? Here, \( x_i \) is independent and identically distributed (iid) with a variance of \( \sigma^2 \).

**Note:** Make sure to comment on the histogram's shape and its properties.
