let µ = E (X). The variance of X can be expressed as: V ar(X) = E X 2 − µ2 7. TRUE For random variables Y and X‚ the variance of Y conditional on X = x is given by: V ar(Y |X = x) = E Y 2 |x − [E (Y |x)]2 8. TRUE An estimator‚ W ‚ of θ is an unbiased estimator if E (W ) = θ for all possible values of θ. 9. FALSE The central limit theorem states that the average from a random sample for any population (with finite variance) when it is standardized‚ by subtracting the mean and then dividing by the

modified Food‚ is food that has been well genetically altered. Furthermore‚ they are foods products from genetically modified organisms that have had their DNA changed through genetic engineering which the DNA is the chemical inside the nucleus of a cell that transmits the genetic orders for making living organisms. So‚ Genetic engineering can be completed with plants and animals like for example‚ the most mutual modified food that resulting from plants are soybean‚ canola‚ cotton seed oil and corn
