1. A CI is desired for the true average stray-load loss (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 = 3.0. a. Compute a 99% CI for when n = 100 and x = 60. b. Compute an 82% CI for when n = 100 and x = 60. C. How large must n be if the width of the 99% interval for is to be 1.0?
