A CI is desired for the true average stray-load loss μ (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 stray-load loss is normally distributed with o = 3.0 . a. Compute a 95% CI for u when n = 25 and x = 58.3. b. Compute a 95% CI for µ when n = 100 and x = 58.3.
