Which of the following is NOT true when dealing with independent samples? Choose the correct answer below. A. The confidence interval estimate of µ 1-µ 2 is ( x 1 - x 2 ) - E < ( µ 1 - µ 2 ) < ( x 1 - x 2 ) + E. B. When making an inference about the two means, the P-value and traditional methods of hypothesis testing result in the same conclusion as the confidence interval method. C. The variance of the differences between two independent random variables equals the variance of the first random variable - the variance of the second random variable. D. The null hypothesis µ 1=µ 2 or µ 1 - µ 2 = 0 can be tested using the P-value method, the traditional method, or by determining if the confidence interval limits for µ 1-µ 2 contain 0.
