8.4.28 Question Help A random sample of size 36 is taken from a normal population having a mean of 85 and a standard deviation of 7. A second random sample of size 64 is taken from a different normal population having a mean of 70 and a standard deviation of 3. Find the probability that the sample mean computed from the 36 measurements will exceed the sample mean computed from the 64 measurements by at least 12.9 but less than 15.7. Assume the difference of the means to be measured to the nearest tenth.
