precision 1. The measurement, x, is an unbiased estimate of u and has o. Expand x2 in a Taylor series about the point x = μ. Hence show that, if the coefficient of variation of x is small, the expected value of z = x² is given by u²+o² and that the coefficient of variation of z is approximately twice as large as that of x.
