Assume that newborn girls have birth weights with a mean of 304? grams and a standard deviation of 1'15 grams. Arandom sample of 100 newbom girls is obtained and they have a mean birth weight of 2858 grams. What is the probability of randomly selecting another 100 newbom girls and getting a mean birth weight that is 2868 grams or lower? Does it seem like a sample mean of 2368 grams is unusual? The probability of getting a mean birth weight that is 2368 grams or lower is :l. (Round to four decimal places as needed.)
