Problem 3

Using the same list l from Problem 1 and l_avg from problem 2, use a for loop to compute the variance of l. The variance is defined as the average of the square of the deviations from the mean. With the mean 4.286 in l_avg, the deviation of any value from the mean is value - l_avg. The average of these squares, the variance, is 5.63. Your code should work for any list with numerical values; you can't hard-code the length of l or any of its elements.

list l from Problem 1 : l = [1, 2, 3, 4, 5, 7, 8]
