show more The average weight of a chicken egg is 2.25 ounces with a standard deviation of 0.2 ounces. You take a random sample of a dozen eggs. a) What are the mean and standard deviation of the sampling distribution of sample size 12? b) What is the probability that the mean weight of the eggs in the sample will be less than 2.2 ounces? (3 points).
Hens usually begin laying eggs when they are about 6 months old. Young hens tend to lay smaller eggs, often weighing less that the desired minimum weight of 54 grams. a. The average weight of the eggs produced by the young hens is 50.9 grams, and only 28% of their eggs exceed the desired minimum weight.If a Normal model is appropriate, what would you predict the standard deviation of the egg weights be? â5.3 grams b. By the time the hens have reached a year, the eggs they produce average 67.1 grams with a standard deviation of 6.4 grams.
