QUESTION 9 You are conducting a test to see if the weights of newborn babies in a NYC hospital is equal to the expected population mean, 8 pounds. We know that x has a normal distribution with o = 4. You randomly pull data for 36 babies and discover that the x is 7 pounds. You are concerned that the newborns at your hospital are premature and seek to assess if the weight at your hospital is different from the expected population mean. The null hypothesis is the alternate hypothesis is O a. Họ *8; H1 -8 Ob. Ho > 8; Ht < 8 OC Ho <8: H1 > 8 Od. Ho - 8; H1 8
