Unformatted text preview: A) For 1000 numbers, Mean = -0.00103 For 750 numbers, Mean = 0.001855 |-0.00103 |<|0.001855|, therefore the the empirical mean gets closer to 0 as the number of trials increases. For 1000 numbers, Standard Dev = 0.578485 For 750 numbers, Standard Dev = 0.580748 0.577 < 0.578485 < 0.580748 => The Empirical Standard Dev gets closer to 0.577 as the number of trials increases. B) For 1000 numbers, Mean = 1.056398 For 750 numebers ,Mean=1.018908 For 1000 numbers, Standard Error of Sample Variance = 1.025678 For 750 numbers, Standard Error of Sample Variance = 0.935634 (1-1.025678) < (1-0.935634) => The Standard Error of Sample gets closer to 1, as the number of trials increases....
