Answer:
Step-by-step explanation:
Given that the height in  inches, of a randomly chosen American woman is a normal random variable with mean μ = 64 and variance 2 = 7.84. 
X is N(64, 2.8)
Or Z = 
a)  the probability that the height of a randomly chosen woman is between 59.8 and 68.2 inches. 

b) 
c) For 4 women to be height 260 inches is equivalent to 
4x will be normal with mean (64*4) and std dev (2.8*4)
4x is N(266, 11.2) 

d) Z is N(0,1)
E(Z19) = 
since normal distribution is maximum only between 3 std deviations form the mean on either side.
