A confidence interval is desired for the true average stray-load loss μ (measured in 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 the stray-load loss is normally distributed with σ = 3.0.(a) Compute a 95% CI for μ when N = 25 and sample mean = 58.3.(b) Compute a 95% CI for μ when N = 100 and sample mean = 58.3.(c) Compute a 99% CI for μ when N = 100 and sample mean = 58.3.(d) Compute a 82% CI for μ when N = 100 and sample mean = 58.3.(e) How large must N be if the width of the 99% CI for μ is to be 1.0?Expert Answer
