Weight Loss of Newborns An obstetrician read that a newborn baby loses on average 7 ounces in the first two days of his or her life. He feels that in the hospital where he works, the average weight loss of a newborn baby is less than 7 ounces. A random sample of 33 newborn babies has a mean weight loss of 6.6 ounces. The population standard deviation is 1.8 ounces. Is there enough evidence at α=0.05 to support his claim? Assume that the variable is normally distributed. Use the P-value method with a graphing calculator. P-value=
