Question 728379
 The weight of the eggs produced by a certain breed of hen is Normally distributed with a mean of 65 grams and a standard deviation of 5 grams. 
Calculate the probability that a randomly selected egg weighs between 62.5g and 68.75g. Show your work. 
---------------------------
z(62.5) = (62.5-65)/5 = -0.50
z(68.75) = (68.75-65)/5 = 0.75
------------
P(0.62.5<= x <=68.75) = P(-0.5<= z <=0.75) = 0.4649
