We are going to generate a sample independent and uniformly distributed random variables. Use Python to generate 1000 independent realizations of an uniform U (0, 1) random variable, we can denote them by U_1, ..., U_1000, the data is stored in a vector named U. Print U. Use Python to compute the sample mean, the sample variance, and plot the histogram of U_1, ..., U_1000, . Print the sample mean and the sample variance, and display the histogram. Briefly explain why you can tell that this histogram corresponds to the one of a uniform distribution, and how you could verify that graphically
