part 1

1. Write a function to compute the mean ? of a list of integers L of length n.

2. Write a function to compute the variance V of a list of integers L of length n.

This measures the spread or dispersion of the data.

3. Write a function to compute the standard deviation D of a list of integers L

part 2

1. write a function to toss a fair coin; it should return True if the coin toss yields Heads and False if the

coin toss yields Tails.

2. write a function to toss a fair coin 100 times and count the number of heads; (we will call this an

experiment)

3. write a function to repeat this experiment 1000 times, and compute the mean of the # of heads

4. compute the standard deviation of these experiments

Repeat this exercise for a biased coin, with probability

p ? [0,1] of heads.
