Unformatted text preview: X (1) , X (2) , , X ( n ) of a sequence of random experiments is dened by h X i n = 1 n n X j =1 X ( j ) Show that the sample mean follows the following recursion formula: h X i n = h X i n-1 + X ( n )- h X i n-1 n , h X i = 0 3. (3 pts) Use the last expression in Question 2 to calculate the sample mean of the 1000 pseudo random numbers generated in Question for both = 128 and = 126. Plot h X i versus n and determine if the sample mean is converging to any particular value as the number of samples increases or if there is any other trend in the curves. 1...
