Reference no: EM131421938

The ISA Babcock Company supplies poultry farmers with hens, advertising that a mature B300 Layer produces eggs with a mean weight of 60.7 grams. Suppose that egg weights follow a Normal model with standard deviation 3.1 grams.

a) What fraction of the eggs produced by these hens weigh more than 62 grams?

b) What's the probability that a dozen randomly selected eggs average more than 62 grams?

c) Using the 68 95 99.7 Rule, sketch a model of the total weights of a dozen eggs.
