1. At one moment in time, we will observe an e-m wave at several different locations along the x axis. In each case, however, we will only consider the electric field at the point with y coordinate equal to 0. (The first few locations are indicated on the axes below.) х X1 X1 + 1/2 X1 + 2 X1 + 31/2 The electric field vector that we find at coordinate xį is shown in the first box on the left...

We have two independent populations A and B, with means H1 and 42 and variances o and ož, respectively. Parameter of interest is difference 0 = Hi - M2. To estimate the difference 0, we use ê = X - Y, where X and Y are the sample means from the respective populations, based on samples of sizes ni, n2, respectively. Which of the following statements is true? A. E[@] = 0 and Var[@] = o/nı + o2/n2 B. E[@]...
