(choose chapter or problem)

A CI is desired for the true average stray-load loss m (watts)for a certain type of induction motor when the line current isheld at 10 amps for a speed of 1500 rpm. Assume that strayloadloss is normally distributed with .a. Compute a 95% CI for mwhen and .b. Compute a 95% CI for mwhen and .c. Compute a 99% CI for mwhen and .d. Compute an 82% CI for mwhen and .e. How large must n be if the width of the 99% interval form is to be 1.0?
