A CI is desired for the true average stray-load loss μ(watts) for a certain type of induction motor when the line currentis held at 10 amps for a speed of 1500 rpm. Assume that stray-loadloss is normally distributed with σ = 2.2. (Round youranswers to two decimal places.)
(a) Compute a 95% CI for μ when n = 25 andx = 56.7.
(answer,answer) watts
(b) Compute a 95% CI for μ when n = 100 andx = 56.7.
(answer,answer) watts
(c) Compute a 99% CI for μ when n = 100 andx = 56.7.
(answer,answer) watts
(d) Compute an 82% CI for μ when n = 100 andx = 56.7.
(answer,answer) watts
(e) How large must n be if the width of the 99%interval for μ is to be 1.0? (Round your answer up to the nearestwhole number.)
