6. An obstetrician read that a newborn baby loses on average 7 ounces in the rst 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 25 new born babies has a mean weight loss of 6.4 ounces. The population stanm Manon is 1.4 ounces. Is there enough evidence at a = 0.05 to support his claim? (1 1 points) Step 1: Write down the information given using mathematical symbols. Step 2: Identify the null and alternative hypotheses. Step 3: Calculate the test statistic. Clearly indicate if you are finding a \"t\" or \"2\" test statistic. Step 4: Find the critical value and identify the rejection region 0R nd the P-value. Please only use one method. In either case, please identify rejection region or P-value on the standard normal curve. Step 5: Decide to whether to reject H0 or fail to reject H". Step 6: State the conclusion
