The weight of the egg produced by a certain breed of hen is Normally distributed with mean 62 grams and standard deviation 4 grams. Calculate the probability that 12 randomly selected eggs have an average weight between 62g and 65g. Round your answer to the nearest thousandth.

Calculate the probability that a randomly selected egg weighs between 62.5g and 68.75g. Show your work. My work: Dont you need a population of how many eggs are produced by a hen before you start

step-by-step explanation: s

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
