Can someone please explain it to me why my answer is wrong??!!! ASAP???!!!

Extracted text: A CI is desired for the true average stray-load loss u (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 o = 2.9. (Round your answers to two decimal places.) (a) Compute a 95% CI for u when n = 25 and x = 51.2. 50.06 52.34 watts (b) Compute a 95% CI for µ when n = 100 and x = 51.2. 50.63 51.77 watts (c) Compute a 99% CI for u when n = 100 and x = 51.2. 50.45 51.95 watts (d) Compute an 82% CI for µ when n = 100 and x = 51.2. |× ) 2.21 2.99 watts (e) How large must n be if the width of the 99% interval for u is to be 1.0? (Round your answer up to the nearest whole number.) n = 56 You may need to use the appropriate table in the Appendix of Tables to answer this question. Need Help? Read It
