14. According to the pediatric literature, babies begin to crawl on average at u = 48 months with a standard deviation of o = 19 months. A pediatrician believes that babies are now beginning to crawl at a later age on average, but he lacks proof. He takes a random sample of 40 babies from his practice and finds the average age when crawling began to be x = 50 months. If the p-value is 0.25 and our level of significance is a = 0.05, we should conclude. (1.5 pts) a. There is enough evidence to conclude that the babies in the pediatrician's practice take longer to begin to crawl on average than suggested in the pediatric literature. b. There is not enough evidence to conclude that babies in the pediatrician's practice take longer to begin to crawl on average than suggested in the pediatric literature. c. The results are inconclusive. d. None of the above
