Dr. Osbоurn is reseаrching the effect оf pаrentаl smоking, during the first six months of life, on children’s language learning. He recruits 100 families who had their first child six months earlier. Parents report if both parents smoked, one parent, smoked, or neither parent smoked. Dr. Osbourn then conducts 30-minute home observations every three months starting when the baby is six months old until the baby is 24 months old. At each observation, he records the child’s pre-linguistic and language skills. He predicts that children raised by nonsmoking parents will show superior language skills at 6, 12, and 24 months. A. Identify the Null and alternate hypothesis for Dr. Osbourn’s study (2 points) B. Is this study longitudinal or cross-sectional? How can you tell? Explain why this was a good or bad choice? (4 points)
