A random sample of size 25 is taken from a normal population that has a mean of 80 and a standard deviation of 5. A second random sample of size 36 is taken from a different normal population that has a mean of 75 and a standard deviation of 3. Calculate the probability that the calculated sample mean of the 25 measurements exceeds the calculated sample mean of the 36 measurements by at least 3.4 but less than 5.9. Assume that the differences of the means are measured to the nearest tenth.
