A doctor said that newborns lose an average of 6 ounces in the first few days of their lives. The doctor feels that in the hospital he works in, the average weight loss is less than 6 ounces. A random sample of 30 newborns has a mean weight loss of 5.5 ounces. The population standard deviation is 1.6 ounces. Is there enough evidence at a=0.01 to support the claim?  State the hypothesis and identify the claim Find the critical value Compute the test value Make the decision Summarize the results
