A random sample of size 25 is taken from a nor- mal population having a mean of 80 and a standard deviation of 5. A second rando

m sample of size 36 is taken from a different normal population having a mean of 75 and a standard deviation of 3. Find the probability that the sample mean computed from the 25 measurements will exceed the sample mean com- puted from the 36 measurements by at least 3.4 but less than 5.9. Assume the difference of the means to be measured to the nearest tenth.
