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).
Because of this, there will be slight variations in the weights of eggs in every carton. A dozen extra-large eggs weigh 27 oz. (about 2-1/4 oz. each on average), a dozen large eggs weigh 24 oz. (about 2 ounces each), and a dozen medium eggs weighs 21 oz.
