Question: Calculate the 9 5 % confidence interval for the difference ( mu 1 - mu 2 ) of two population means given the following sampling

Calculate the 95% confidence interval for the difference (mu1-mu2) of two population means given the following sampling results. Population 1 : sample size =17, sample mean =35.69, sample standard deviation =2.25. Population 2: sample size =20, sample mean =18.81, sample standard deviation =3.34.
Your answer:
16.86 mu1-mu216.91
15.43 mu11 mu 218.34
13.20 mu1- mu 220.57
15.00 mu1- mu218.77
16.05 mu11 mu 217.72
14.50 mu1-mu219:27
13.14 mu1- mu 220.63
14.73 mu1- mu219.04
15.64 mu1- mu218.13
15.49 mu11 mu 218.27
