In the classic study of infant attachment, Harlow (1959) placed infant monkeys in cages with two artificial surrogate mothers. One "mother" was made from bare wire mesh and contained the baby bottle from which infants could feed. Other mother was made from soft terry cloth and didn't give any access to food. Harlow observed infant monkeys and recorded how much time per day was spent with each mother. In typical day, infants spent total of 18 hours clinging to one of two mothers. If there were no preference between two, you would expect time to be divided evenly, with average of μ = 9 hours for each of mothers. Though, typical monkey spent around 15 hours per day with terry cloth mother pointing to strong preference for soft, cuddly mother. Assume the sample of n = 9 infant monkeys averaged M = 15.3 hours per day with SS = 216 with terry cloth mother. Is this result adequate to conclude that monkeys spent significantly more time with softer mother than would be expected if there were no preference? Use the two-tailed test with α = .05.
