Step-by-step explanation:
Since the overall 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.
That gives us:
(62.5) = (62.5 - 65) / 5 = -0.50
(68.75) = (68.75 - 65) / 5 = 0.75
Probability(0.62.5<= x <=68.75)
= Probability(-0.5<= z <=0.75)
= 0.4649
