Aci 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 σ = 2.8. (round your answers to two decimal places.)

(a)compute a 95% ci for ? when n = 25 and x = 51.4.

watts

(b) compute a 95% ci for ? when n = 100 and x = 51.4.

, watts

(c) compute a 99% ci for ? when n = 100 and x = 51.4.

watts

(d) compute an 82% ci for ? when n = 100 and x = 51.4.
