A random sample of size 16 is drawn from population that is
normally distributed with mean 12.3 and
variance 17.6. Another random sample of size 11 is drawn from
population that is normally distributed with mean
11.5 and variance 9.8.
(a) Find the P(| ̄X1 − ̄X2|> 1.8).
(b) Find c such that P( ̄X1 − ̄X2 < c) = 0.85.
