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=3.16.

(Round your answers to two decimal places. You must enter the LOWER BOUND first then the UPPER BOUND second.)

(a) Compute a95%CI forwhenn= 25 andx=50.25.

,

watts

(b) Compute a95%CI forwhenn= 100 andx=50.25.

,

watts

(c) Compute a99%CI forwhenn= 100 andx=50.25.

,

watts

(d) How large mustnbe if thewidthof the99%interval foris to be 1.0? (Round your answer up to the nearest whole number.)
