Please solve d and e 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 a = 2.9. (Round your answers to two decimal places.)(a) Compute a 95% CI for μ when n = 25 and x = 52.9.watts(b) Compute a 95% CI for μ when n = 100 and x = 52.9.watts(c) Compute a 99% CI for μ when n = 100 and x = 52.9.watts(d) Compute an 82% CI for when n = 100 and x = 52.9.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 nearest whole number.)n=You may need to use the appropriate table in the Appendix of Tables to answer this question.

Given that Sample size n =100 Sample mean=52.9 Population standard deviation =2.9 Solution:- (d) The critical value for α=0.18 is Zc=1.341 For two tailed test. (Calculated from excel) Formula used for critical value. =NORM.S.INV(1-0.18/2) 82% C.I = ( x̄ ± Zc× ?/√n) = ( 52.9±1.341× 2.9/√100) =(52.51 , 53.29 )(e) Margin of error =E =1 The critical value for α=0.01 is Zc=2.576 For two tailed test. (Calculated from excel) Formula used for critical value. =NORM.S.INV(1-0.01/2) Sample size required n. n= (Zc×?/E)2 = (2.576×2.9/1.0)2 =55.80687616 n=56
