Write a program stats.py that writes the mean mu, variance Var. and standard deviation sigma of the floats x_1, x_2..., x_n supplied as command-line arguments, computed using the formulae: mu = x_1 + x_2 + ... + x_n Var = (x_1 - mu)^2 + (x_2 - mu)^2 + ... + (x_n - mu)^2, and sigma = Squareroot Var. $ python stats.py 77 41 3 76 19 48 92 10 26 63 45.5 856.65 29.26858384 # scats.py: writes the mean, variance, and standard deviation of # the floats x_1, x_2, \dots, x_n supplied as command-1ine # arguments. import stdio import sys # Create a list a consisting of the floats from the command line. a = for V in # Define a variable n and set it to the number of elements in a. # Compute the average of a into a variable avg. avg = for V in a: # Compute the variance of a into a variable var. var = for V in a: # Compute the standard deviation of a into a variable std. std = # Write avg, var, and std. 6.
