A random sample of size n₁ = 16 is selected from a normal population with a mean of 75 and a standard deviation of 8. A second random sample of size n2 = 9 is taken from another nor-mal population with a mean of 70 and standard deviation 12. Let X₁ and X2 be the two sample means. Find P(X₁ – X2 > 5.5).
Let P(Z< 0.11) = 0.5438.
