5. Sample values from an experiment often need to be smoothed out. One approach is to replace each value with the mean of the previous n values, this is called the simple moving average. Implement a function, smooth (values, n ) that carries out this operation. The variable values is a list of numbers and n is the size of the moving average. The function should return a new list with the smoothed data. The new list should have n 1 fewer elements than the original list. For example, smooth ([ 3 , 5 , 1 , 5 , 6 , 8 , 9 , 10 , 15 , 3], 3) should return [ 3.0 , 3.7 , 4.0 , 6.3 , 7.7 , 9.0 , 11.3 , 9.3 ] ..
