I just became a CNA and I have an interview at a doctors office...and I will work with other CNA's soooo I'm not sure where you are getting you information. CNAs do not typically work in doctors offices or clinics. CNAs work in rehabilitation centers and nursing homes.
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).
Answer: The eggs sizes are more consistent for the younger hens because their standard deviation is smaller. d) A certain poultry farmer finds that 9% of his eggs are underweight and that 10% weigh over 73 grams.Estimate the mean and standard deviation of the eggs.Solution: Draw a picture of this scenario and mark the graph with the known information: Find the z-scores that correspond with each of these weights. For the weight of 51, look for the value closest to .0900 in the Normal distribution table.oung hens tend to solve smaller eggs, often weighing less than the desired minimum weight of 51 grams. a) The average weight of the eggs produces by the young hens is 50.6 grams, and only 29% of their eggs exceed the desired minimum weight.
