Question 4: The MSE will be the sum of the ________ of the range error plus the variance of the azimuth error plus the covariance of the range error with the azimuth error plus the square of the bias.

Question 5: ________ with this distribution behavior tend to cluster around the aim point, with most reasonably close, progressively fewer and fewer further away, and very few at long distance.

Question 6: Munitions may also have larger ________ of range errors than the standard deviation of azimuth (deflection) errors, resulting in an elliptical confidence region.
