Assume that newborn girls have birth weights with a mean of 3033 grams and a standard deviation of 716 grams. A random sample of 100 newborn girls is obtained and they have a mean birth weight of 2842 grams. What is the probability of randomly selecting another 100 newborn girls and getting a mean birth weight that is 2842 grams or lower? Does it seem like a sample mean of 2342 grams is unusual? The probability of getting a mean birth weight that is 2842 grams or lower is 0.0038 . (Round to four decimal places as needed.) Since the sample mean lies : than 2 standard deviations away from the mean, getting a mean birth weight that is grams or lower V unusual. (Type an integer or a decimal. Do not round.)
