From September 2000 to August 2002, 30 premature infants were admitted to the neonatal ICU of Southern Philippines Medical Center. They were divided into groups wherein one group was treated with new methodologies of assisted ventilation and the other was treated with the standard. The results of their weight in grams are shown on the right. At 90% confidence level, test the claim that the new treatment is more effective than the standard by using the traditional of hypothesis testing. 1. Give the null hypothesis in symbols. 2. Give the alternative hypothesis in symbols. 3.Identify the tail of the test.
