In grading eggs into small, medium and large, Margi farms packs the eggs that weigh more than 4.25 ounces in packages marked ” large” and the eggs that weigh less than 2.45 ounces in packages marked ” small” the remainder are packed in packages marked ” medium”. If a day’s packaging contained 10.56% large and 4.01% small eggs, calculate the meanand the standard deviationof the weights of eggs ( Assume that the distribution egg weights is normal)
The solution file is attached.
x1 = 4.25, x2 = 2.45, z = (x – )/ …
The mean and standard deviation are calculated with the help of two equations.
