Given two independent normal distributions with s₁² - s₂² = 100,μ₁ = μ₂ = 50,n₁ = n₂ = 50,the sampling distribution of the mean difference will have a mean of _________. A)1 B)0 C)50 D)100

Question

Quizplus · Accepted Answer

Since the two distributions have the same mean of 50, their difference will have a mean of 0. Therefore, the sampling distribution of the mean difference will also have a mean of 0.
