Calculate the 95% confidence interval for the difference (mul-mu2) of two population means given the following sampling results. Population 1: sample size = 15, sample mean = 30.95, sample standard deviation = 4.07. Population 2: sample size = 11, sample mean = 14.38, sample standard deviation = 4.07. Your answer: O 13.79 < mul-mu2 < 19.36 13.97 < mul-mu2 < 19.18 O 12.83 < mul-mu2 <20.32 11.14 <mul-mu2 < 22.01 O 16.31 <mul-mu2 < 16.84 O 11.33 < mul-mu2<21.82 o...
Question 5 Calculate the two-sided 95% confidence interval for the population standard deviation (sigma) given that a sample of size n=10 yields a sample standard deviation of 12.29. Your answer: O 11.64 < sigma <33.17 8.45 < Sigma <22.44 10.63 < Sigma < 15.74 9.29 < Sigma <23.64 5.28 < sigma <29.78 1.08 < sigma <31.24 11.07 < sigma 16.03 12.20 < Sigma 19.97 14,71 < sigma < 10,43 11.30 < sigma < 13.61
