Researchers are interested in the mean age of a certain population. A random sample of 16 individuals drawn from the population of interest has a sample mean of 27 with sample standard deviation of 6.3 and the significance level is 0.1. The researchers want to know if they can conclude that the mean is different from 30 years. The null and alternative hypotheses are given as: Hon = 30 H:16 30 What should the researchers conclude? a. They should not reject Ho and conclude that there is no enough evidence to say # # 30. ob. They should accept H, and conclude that there is enough evidence to say # # 30. O c. non of them od. They should reject H and conclude that there is enough evidence to say u = 30. Oe. They should accept H, and conclude that there is no enough evidence to say # 30. Next page Sec 2 (Dr. LINE ON A
