A random sample of size n1 = 13 is selected from a normal population with a mean of 76 and a standard deviation of 7. A second random sample of size n2 = 10 is taken from another normal population with mean 68 and standard deviation 14. Let and be the two sample means. Find: (a) The probability that exceeds 3. (b) The probability that 4.5 5.5.
