This please :)

1. Let u be true mean stray-load loss (measured in watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1,500 rpm. Assume that stray-load loss is normally distributed with o = 3.0. The estimated sample mean is x = 58.3 (a) Compute a 95% and a 99% CI for u when n = 25. (b) Compute a 95% and a 99% CI for u when n = 10. Now assume that o is unknown and gets estimated by the sample SD s = 4.3. (c) Compute a 95% and a 99% CI for u when n = 25. (d) Compute a 95% and a 99% CI for u when n = 10. Compare your answers for fixed n, and fixed confidence level, respectively
