A CI is desired for the true average stray-load loss μ (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 = 2.0. (Round your answers to two decimal places.)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?
