A 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 stray-load loss is normally distributed with o = 2.2. (Round your answers to two decimal places. ) (a) Compute a 95% CI for u when n = 25 and x = 58.7. watts (b) Compute a 95% CI for u when n = 100 and x = 58.7. watts (c) Compute a 99% CI for u when n = 100 and x = 58.7. watts (d) Compute an 82% CI for u when n = 100 and x = 58.7. watts (e) How large must n be if the width of the 99% interval for u is to be 1.0? (Round your answer up to the nearest whole number.) n =
