3. Confidence intervals A radar system measures the azimuth angle of an approaching aircraft. Statistically this angle observation can be modeled as a Gaussian distribution. (In other words, don't sweat the detail that an angle measurement is only between 0° and 360°.) The accuracy of the radar hardware is given by the variance o. Tests show that the standard deviation is o=3º. The design specification states that the final system performance must measure azimuth angle to a tolerance of +0.5º. Thus, an overall interval of 1° is required. How many observations, N, must be averaged to produce a 99% confidence interval that the final azimuth measurement is within the 1° interval required?
