Question: 8. One sample with n = 25 is randomized from a normal population with mean = 80 and S.D. = 5. Another sample with n

8. One sample with n = 25 is randomized from a normal population with mean = 80 and S.D. = 5. Another sample with n = 36 is randomized from another normal population with mean = 75 and S.D. = 3. Find the probability that the sample mean of the 1st sample is larger than the sample mean of the 2nd sample by at least 3.4 but less than 5.9
