Assume that newborn girls have birth weights with a mean of 3055 grams and a standard deviation of 692 grams. A random sample of 100 newborn girls is obtained and they have a mean birth weight of 2869 grams. What is the probability of randomly selecting another 100 newborn girls and getting a mean birth weight that is 2869 grams or lower? Does it seem like a sample mean of 2869 grams is unusual?
