Aconfidence interval (ci) is desired for the true average stray-load loss u (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. assume that strayload loss is normally distributed with o = 3.0. (1). construct a 95% ci for u when n = 25 and x = 58.3. (10 points) (2). construct a 95% ci for u when n = 100 and 1 = 58.3. (10 points) (3). construct a 99% ci for u when n = 100 and x = 58.3. (10 points) (4). how large must n be if the half-width of the 99% interval for u is to be 0.5? (10 points)
